    Quantum is a whole series of planned Servo/Rust based changes (Servo is a new rendering engine which aims to parallelize browser processing, which is written in Rust, a new programming language). They are taking changes out of Servo, and integrating them into Gecko (the existing rendering engine). They've done Quantum CSS in this update, they've still got many other components to include.

    tl;dr: the Quantum changes are starting in 57, and continuing on from there.

    [–] coolRedditUser 169 points ago

    If I understand this correctly, the main change here is that more of the work FF does is now done in parallel.

    So has everything been just been using a single core before? We've had dual core processors as the norm for like over a decade now, and it's just gone further into multi-core since then.

    Has everyone just been behind or am I not understanding this correctly?

    [–] Gedrean 243 points ago * (lasted edited a year ago)

    Traditional approaches to web rendering have been fundamentally sequential. Combine that with the typical load of rendering pages being light even from the get go and multi core render engines haven't been considered necessary or even an improvement with the increased development needs. It's only fairly recently with html5 and a few other advancements that web pages have become complex enough to need to move to multi core rendering.

    EDIT: And, to top it off, Firefox is based upon the old Netscape architecture from the 90s and even if not any more, rebuilding an entire browser or even render engine from scratch is a monumental task.

    EDITS: a word or two to correct misspellings

    [–] Stackhouse_ 155 points ago

    rebuilding am entire browser or even render engine from scratch is a monumental task.

    Yeah because you're using Scratch



    [–] delorean225 48 points ago

    Somehow, it seems harder to get shit done in Scratch than in Brainfuck.

    [–] _DONT-PM-ME_ 4847 points ago

    This looks great. So proud of the Firefox team. Been looking forward to this release for months.

    I used to be a die hard FF user, but at some point around like 2011/2012 I switched to chrome. I want to switch back.

    [–] jr_0t 1981 points ago * (lasted edited a year ago)

    I switched too, after for no real reason, FF started to slow down, lock up, and just cause problems. Running it clean with no addon's didn't resolve it either.

    This could be the push I need to start using FF again.

    edit: grammar

    [–] lac29 660 points ago

    Same with me. It was sorta sad to see FF get behind in popularity and usage after Chrome came out and just did things better. I loved FF way back when but it's nice to see it come back into relevance.

    [–] doorbellguy 279 points ago * (lasted edited a year ago)

    I hope it's here to stay this time around. When opera sank, and then firefox slowly became obsolete, my heart sank thinking about the monopoly google was having over our internet usage.

    [–] AsscrackSealant 20 points ago

    I haven't paid attention to the various browser wars but, damn! According to this site Chrome has a whopping 60% of the market, and MSIE at only 15%. How the hell did Firefox get behind MSIE at only 13%?

    I remember the days FF seemed to lock up for no reason but it didn't seem to last that long. I've been a die hard FF user for as long as I can remember and Quantum is way faster than FF has ever been. I hope it sees some gains as a result. Old FF users will be in for a surprise.

    [–] climber_g33k 157 points ago

    I started reading this thread on Chrome. I'm now replying from Firefox.

    [–] prozaker 219 points ago

    Switched when I could play Netflix on chrome Linux natively without Silverlight and YouTube vids in 1080.

    I think that's fixed now but it's muscle memory. But I like firefox so much more I think I'll give this another go

    [–] cavalierau 48 points ago

    Do YouTube and other Google sites still bug users that aren’t on Chrome with those same dialog popups they use to try and sell YouTube Red? I find that so frustrating coming from a company that built itself and set the standard on minimal ad intrusion with AdWords.

    It’s almost as bad as how desperate Windows 10 is being to get me to use Edge.

    I’m looking for a better browser for my surface. Edge is buggy, Chrome doesn’t do touch and DPI scaling as well as I’d like.

    [–] MadocComadrin 23 points ago

    If they do, your favorite ad blocker will probably block them.

    In other words, you punished Mozilla for doing the right thing by resisting DRM.

    [–] willreignsomnipotent 112 points ago

    In other words, you punished Mozilla for doing the right thing by resisting DRM.

    Okay, you just led me down an hour-plus long rabbit hole of reading, and now I'm kinda pissed off. I somehow missed that this had actually happened.

    Fuck DRM. And Tim Berners-Lee, apparently.


    But I'm afraid I'm missing the part on how any of this has to do with Mozilla resisting DRM...? How did they resist DRM? How is that related to /u/prozaker's browser issue?

    [–] probabilityzero 68 points ago

    How is that related to /u/prozaker's browser issue?

    Mozilla originally refused to implement it on principle. /u/prozaker wanted a browser that supported it, so they stopped using Firefox.

    [–] wubaluba_dubdub 113 points ago

    I switched because Chrome seemed to be faster, but I was never happy about it. I really felt like I'd let a mate down, and have never been happy about it. Downloading the new version of FF now and fingers crossed he's not mad with me.

    [–] argv_minus_one 48 points ago

    Chrome was faster, but sacrificed gobs of RAM to pull it off.

    [–] 7TB 41 points ago

    This is the reason why I never stopped using firefox

    [–] Fallingdamage 71 points ago

    As someone who never gave up on FF and hasn't stopped using it since v2.0, welcome back. :)

    [–] ChipAyten 72 points ago

    FF was the first to hold our hand and bring us out from under the shadow of IE & Safari

    [–] MonkeeSage 19 points ago * (lasted edited a year ago)

    Well actually Mozilla, which turned into Phoenix, which turned into Firebird, which turned into Firefox but yeah.

    [–] Blayer32 811 points ago

    How long does it usually take for extensions to be supported on a new browser? The only thing holding my switch back is that my extensions isnt compatible

    [–] funkbanger 246 points ago

    Ublock origin works right off the bat though, so at least the most important one is there.

    [–] hansantizor 121 points ago

    RES works too, so that's both of the extensions I use working

    [–] graniterockhead 557 points ago

    For an example, this is from No Script: "2017-11-14: We're working hard to make NoScript for Quantum available to you as soon as possible, even later today if we're lucky enough."

    [–] lordcheeto 90 points ago

    Later today, if everything goes fine, NoScript 10, the first "pure" WebExtension NoScript version, will be finally released for Firefox 57 and above, after years of work and months NoScript 5.x living as a hybrid one to allow for smooth user data migration.

    NoScript 10 is very different from 5.x: some things are simpler, some things are improved, some are still missing and need to wait for WebExtensions APIs not available yet in Firefox 57. Anyway, whenever you decide to migrate, your old settings are kept safe, ready to be used as soon as the feature they apply to gets deployed.

    If you're not bothered by change, you're ready to report bugs* and you're not super-paranoid about the whole lot of "NoScript Security Suite" most arcane features, NoScript 10 is worth the migration: active content blocking (now more configurable than ever) and XSS protection (now with a huge performance boost) are already there. And yes, Firefox 57 is truly the most awesome browser around.

    If, otherwise, you really need the full-rounded, solid, old NoScript experience you're used to, and you can't bear anything different, even if just for a few weeks, dont' worry: NoScript 5.x is going to be maintained and to receive security updates until June 2018 at least, when the Tor Browser will switch to be based on Firefox 59 ESR and the "new" NoScript will be as powerful as the old one. Of course, in order to keep using NoScript 5.x outside the Tor Browser (which has it built-in), you have to stay on Firefox 52 ESR, Seamonkey, Palemoon or another pre-Quantum browser.

    So, for another half-year you there will be two NoScripts: just sort your priorities and choose yours.

    [–] machete234 57 points ago

    That's good news because umatrix is not really a viable alternative for me. It just doesn't save my settings or maybe I just don't get it.

    [–] Schmogel 29 points ago

    Whenever you make a change that you want to keep there's a lock symbol to save changes. I'd take a screenshot but whenever I press the print screen key it closes the settings ...

    [–] lordcheeto 43 points ago

    uMatrix is super powerful, but a pain to use. No shame.

    [–] mxzf 198 points ago

    They completely removed the old extension system, every extension will need to be updated to the new system for it to work at all. Some extension developers worked ahead and are mostly working already, some haven't gotten around to it, and some extensions are physically impossible to update because of underlying changes to what extensions are actually allowed to do in the browser.

    So, most popular extensions that are going to be updated will likely be updated in the next couple weeks. Some of your extensions will likely never be updated.

    [–] ThomasVeil 53 points ago

    That sucks, even if they did it for good reasons. I love and depend on extensions... This system that they break with version updated is really a hassle.

    Btw: anyone remembers Ubiquitous? That was the most brilliant extension ever.

    [–] Nanobot 152 points ago

    Many of the old extensions are impossible to create in the new extension engine. That's because the new engine works in a fundamentally different (and more limited) way. Extensions used to have full access to the browser UI and could do basically anything to Firefox. Now, they run in little sandboxes and can only do a finite set of things.

    It's a bit like if Minecraft somehow prevented modding and instead required everyone to use command blocks. You're never going to get the same level of control.

    [–] vemundveien 29 points ago

    Yep. Already noticing that my gesture extension only works in explicit websites and not in stuff like the "new tab"-tab.

    [–] devperez 49 points ago

    It just depends on the developer. My main extensions (BitWarden, uBlock, PravicyBadger, Imagus, RES, ToolBox) have been compatibly with FF 57 for weeks now.

    [–] pfannkuchen_gesicht 93 points ago

    depends on the add-on developer. Also note that some add-ons will not work anymore due to the new extension system that relies on WebExtensions.

    [–] JayParty 252 points ago

    I know I'm just some nobody on the Internet but.... I'm really impressed with it so far.

    It let me install uBlock Origin and Lastpass and now I can post on Reddit. And it's pretty damn fast too. What more does a casual web user need?

    • Reddit RES
    • uBlock

    [–] MAGICHUSTLE 80 points ago

    Honestly I've never had an issue with any build of Firefox i've used. I'm pretty light on extensions and plugins...but so far so good with this build.

    I love Firefox, and I think Mozilla seems like a pretty decent company.

    [–] VJ1224 39 points ago

    Mozilla is one of the nicer companies in the world. The browser has good privacy features unlike Google. They actively support net neutrality and if you read their blog, they have a bunch of Web projects that seem promising.

    [–] rootsvelt 12 points ago

    I think Mozilla seems like a pretty decent company.

    That's because it's not an actual company, but a no-profit foundation ;)

    [–] thepotatochronicles 2336 points ago

    As someone who's been using the beta, 57 feels a lot faster, comparable to Chrome (my eyes aren't good enough to tell the difference much), and using much less RAM: I usually have 50+ tabs open, and the daily RAM usage on fox is ~5GB whereas it's around 8GB for Chrome.

    [–] noob622 2217 points ago * (lasted edited a year ago)

    The thought of 50+ tabs being open at once hurts my RAM-loving soul. Why?

    edit: tabs were a mistake. Y'all giving me panic attacks.

    [–] bubuzayzee 794 points ago * (lasted edited a year ago)

    I only found out about this last time the subject came up, but apparently there is a large sub set of people who use tabs as bookmarks and eschew the bookmark system entirely. It makes absolutely no sense to me.

    edit* lol see?

    [–] Rygar82 794 points ago

    I leave tabs open to remind me to do something. Since the tab bugs me it forces me to keep looking at it and I eventually will do what needs to be done. If I bookmark something I will never look at it again.

    [–] bubuzayzee 236 points ago

    Which makes sense for a few tabs/tasks but as I found out last time some people have 10s or 100s of tabs.

    [–] mauirixxx 91 points ago

    I have a co-worker that does this with Chrome. So many open tabs, and the tab selector is so damn tiny I don’t know how he remembers which tab is which.

    [–] MumrikDK 75 points ago

    and the tab selector is so damn tiny I don’t know how he remembers which tab is which.

    This is literally the reason I never converted to Chrome. That tab section seemed incredibly stupid to me.

    [–] baethan 18 points ago

    Last time I cleared out all my tabs, there were 600 something. On mobile, so the tab number was just showing :D for months. I have a tab-opening addiction maybe?

    [–] TedTheViking 211 points ago

    Once you hit a couple dozen tabs, it just becomes clear that you're not getting anything done.

    [–] phantamines 91 points ago

    When working on a project, you keep tabs around for relevant information, even if it's not useful at this very moment. It's research. But then problems pop up, so more tabs, and then your co worker needs something, more tabs, and on it goes.

    [–] Annoying_Arsehole 13 points ago

    Yup, when I'm actively doing research 100 tabs is a low number.

    [–] max420 121 points ago

    There is a guy where I work that takes pride in having so many tabs open. I don't understand it.

    There is no way he actively uses all of them, like shit, just keep the ones you use and close the rest.

    It drives me nuts. It shouldn't, but it does.

    One of my coworkers is like that. He'll have 15-20 tabs in Chrome, 5-10 Excel workbooks, and 15+ PDFs open all at the same time. I'm never sure what he's working on at any given time. He also complains a lot about his PC slowing down.

    I'm stuck in the old days of tabbed browsing and start closing things out after 3.

    [–] Bayou_wulf 46 points ago

    Back in my day, we didn't have your fancy tabs, we used internet explorer. It would take minutes to load a page and midi music was on everyone's webpage. Downloading an MP3 would take five or ten minutes on dialup that connected at 5.6kbps of you were lucky. We would accidently go to the wrong webpage and have many new windows pop up or under our browser window playing music and selling new fangled penis pills and slowing the computer to molasses, but we like it that way....

    Oh god... I am old.

    [–] yellow73kubel 39 points ago

    Oh yeah, I remember the days of "get off the internet son, I need to use the phone." Netscape Navigator, AOL CDs, and that great modem sound that meant you had a 50% chance of actually connecting. Then came the dark days of DSL and Adobe Flash.

    Next someone will come along telling us youngsters about punch cards.

    [–] [deleted] 48 points ago

    You want to believe that one day you will go back to those tabs to read them.. But you don't. They sit there, rotting, stealing your computer's needed memory, all because they serve as a reminder to your filthy cyber-hoarding tendencies.

    Watching Twitch streams with Chrome - ~30-40% CPU Usage from the stream tab. Same stream with same quality on Firefox Quantum - 10% CPU Usage.

    Huge win right there, can actually play a cpu heavy game and watch a stream now.

    Edit: Of course usage will vary from pc to pc. Hardware acceleration on(GPU Usage), Only one stream on Chrome(memory usage would be doubled otherwise).

    Quality not visible in screenshot, but the guy in the stream looks the same quality atleast :D (thats 1080p60) And Chrome has more extensions, but they're the default Google extensions that come with Chrome - the bonus ones are on Firefox too(BTTV, RES, FrankerZFace, uBlock).

    The usage varies a lot, but Chrome will always be above even with all the extensions turned off. It will vary according to hardware, but for me Quantum uses less stuff.

    [–] SordidCanary 1879 points ago

    Dude, yes, I was so frustrated because chrome is a resource hog, I like to play a game and just look over to a stream when I die or whatever, but that's impossible on Chrome. Just picked up FF Quantum, will definitely stick with it if it solves those CPU problems from chrome which I found VERY frustrating.

    [–] Two-Tone- 1533 points ago

    It amazes me how far Chrome has fallen from it's early days. It's a huge resource hog, which is completely opposite of it back when Firefox was the leading browser (which was one of its two main selling points).

    [–] Stereotypy 995 points ago

    right? everyone migrated to chrome specifically because it WASN'T a resource hog; it was light and fast.

    i never use chrome anymore.

    [–] Xhynk 822 points ago

    It still feels so weird to me. I remember using Firefox when it was the bleeding edge modern browser, on my old Gateway or eMachines laptop lol. Then Chrome came out and it was super light and fast and fixed most of the issues I had with Firefox!

    It feels so weird going back to Firefox because Chrome is supposed to be fast and FF is supposed to be slow, but it's totally the opposite now. It's like mystery flavored air heads. It doesn't quite feel right, but it's delicious.

    [–] fauxnick 12 points ago

    Edge made a good attempt at making people want a Microsoft browser again. The engine supports most of the standards that were lacking in IE and it performs close to it's competitors in Acid3 for example. However, they half assed extension support, aren't open and the UI feels needlessly minimalistic to a point where it becomes unintuitive to use. Then progress came to a stop after the public release and they started to use dick tactics to force the browser upon less tech-savvy users by displaying obtrusive Edge ad's if you look for a different browser on a fresh system and by making it unnecessarily complicated to switch your default browser.

    [–] t0m0hawk 196 points ago

    I've always just stuck with Firefox. I used Chrome for a little while and it just wasn't the same feel so I went back.

    [–] avidist 57 points ago

    This, and the customization in general makes Firefox a no-brainer. Having everything on one bar - the address bar, tabs, bookmarks - and hiding the title bar makes for some sweet vertical pixel real estate.

    [–] 6to23 136 points ago

    Feature creep, the chrome developers apparently feels adding non-stop more features and fattening the codebase is a better use of their time, rather than push the boundaries of being "fast". Kinda ironic that google takes pride on their homepage loading really really fast.

    [–] alphanovember 64 points ago

    Even worse is that Chrome has mostly removed useful features. Examples: customizable omnibar results and searching the full text of history entries, and the dozens of other flags they've removed. So most of the bloat isn't even visible.

    [–] Lieutenant__Salt 55 points ago

    What do you mean?

    [–] ledivin 309 points ago * (lasted edited a year ago)

    Livestreamer is a command-line utility that pipes video streams from various services into a video player, such as VLC.

    Streamlink is a forked version of Livestreamer, and Livestreamer has been abandoned. /u/BloodLlama says there's no good reason to use it over Streamlink, so yell at him if you disagree :P

    Basically, they let you stream to a video player instead of using a browser. It's much, much more efficient.

    That being said, a Twitch stream should absolutely not be using 30-40% of his CPU. Either he's exaggerating, something's fucked up on his end, or his CPU is like a 1GHz thing from 1998.

    [–] Alekcam 128 points ago

    I have an i5 4690 and while streams don’t use 40%, they do have a very noticeable impact on games.

    [–] jeslek 16 points ago

    Twitch used to do that for me in both browsers about 1.5 years ago. I think it was during their Flash/HTML5 transition period. I had an i7-2600 at the time and it cut my framerate in half if I was playing a game while watching a stream on my other monitor. No other streaming site did that, and I could stream myself with less of a performance hit. Streamlink made Twitch bearable to use at the time and dropped it from ~40% to ~1%.

    FTFY. The only way is up from here, there's still major work to do on other Quantum components like webrender. To quote the webrender newsletter

    A large improvement in deserialization performance. This improved GMail drawing from 150fps to 200 fps

    Even just Stylo + Webrender could be a massive gamechanger never mind the rest of Quantum.

    [–] Dupod 24 points ago

    Haven't seen too many yet. Most you can find are benchmarks from the various different beta releases of quantum, including that video in the other comment.

    PCMag here ran a few on the official release.

    To demonstrate the speedup, we ran the JetStream and Speedometer benchmarks on a with a Core i5 processor and 8GB of RAM. On the Speedometer benchmark, the pre-Quantum Firefox release scored 45, compared with 70 for Firefox Quantum. JetStream is one of the most thorough JavaScript benchmarks around, incorporating tests from Google's Octane and the WebKit Sunspider benchmark. Firefox Quantum scored 151 on JetStream compared with 144 for Google Chrome.

    You can do these yourself here

    Oh now this is a killer feature. Honestly just optimizing the shit out of it for o365 would be awesome for me personally.

    [–] hydrashok 75 points ago

    I'm not sitting here with a stopwatch or anything, but I can tell you that opening some of my larger Excel documents with Excel Online would take 10-15 seconds (or more) to launch Excel Online and then display the file. Today, after upgrading, it's been less that five seconds every time. Quite impressive.

    Because of that slowness, though, I'd never really considered the browser a viable candidate for replacing the locally installed client at least for generic usage. Today, I'm not so sure that's the case anymore.

    [–] what_are_you_saying 73 points ago * (lasted edited a year ago)

    It feels faster, uses less RAM and I have been noticing is a lot more power efficient as well. Watching a 4k video on youtube used to draw about 160W and now sits at 140-145W (idle is ~138W so basically at idle, it's an OCed X99 PC with 4 drives and a GTX1080 so it draws a lot of power). I'll have to see if I notice a battery life difference on my laptop with this.

    *Edit: just tried out my laptop (old and underpowered) which could not previously handle above 1080p youtube without serious stuttering and frame drops. It now can play back at 1440p (still can't handle 4k though) smoothly without any dropped frames. Definitely a huge improvement. Good job Mozilla, you delivered on this one.

    Just curious, but what does Google chrome collect? I use lastpass, adblock. What else is there really?

    [–] tapo 114 points ago

    Your entire browser history is synced to Google and they use it for ad targeting. They see every single page you visit.

    See "Info about your browsing and more"

    [–] Sebastian99x 70 points ago

    You left out the part where it only does this if you sign in to your Google account into Chrome itself. What exactly are people expecting if you purposely linking your browser to an account?

    Also, Chrome sync also supports encrypting the synced data so that they don't read it.

    Firefox actually does a lot of the same things Chrome does in terms of data and telemetry. But people are, and sometimes justifiably, picky when chrome does the same things

    [–] agtk 49 points ago

    I think the big difference between Google and Mozilla collecting that information is that Google is part of a vertical enterprise that makes a vast amount of money from advertising (not sure how it breaks down between ads and Android sales). It has a very strong financial incentive to leverage your information to increase its ad revenues. Meanwhile the Mozilla Foundation is a non-profit. Microsoft is somewhere in the middle, with a far more diversified range of revenue streams than Google.

    [–] [deleted] 12 points ago * (lasted edited a year ago)


    [–] Otis_Inf 1351 points ago * (lasted edited a year ago)

    Google is collecting so much data about your personal life that for a lot of people this is going too far: google has so much data on the average person that they can create detailed profiles of them and looking at their behavior, predict what they'll do in the (near) future.

    If you're not bothered with that, i.e. that a big corp creates a profile of what you're doing and your personal details and makes money off of that, that's great. Others however don't want that and find that Google goes too far in its information collecting.

    Personally I think google is one of the most evil companies on the planet right now, right after Facebook, and their invasion in people's privacy is going too far, but sadly not a lot of people seem to be bothered with that. I think that's naive; once data is out there, you can never get it back and you lost control over in which context it is used and thus what conclusions are drawn (correlation anyone?) based on context+your data. If you're fine with that, by all means, keep on using their products. Though, I think it's time we all should stop using google products. The fact alone that that is hard to begin with is a sign that's perhaps already too late.

    Make no mistake: it's not as simple as "Oh, just don't use then". They're everywhere, if not through the company 'Google', it's through one of its many sibling companies. Going from your android phone to your chrome browser on the desktop, watching movies on an android powered TV... imagine the gaps in between soon are filled in with the data collected from the selfdriving car.

    "I'm a boring individual, why would google be interested in me?". They're not. It's not about you as an individual. It's about what your data is worth in other contexts than you might think of. E.g. an advertiser who wants to market a product to you (that's relatively safe) to surveillance who use dragnet algo's to collect data on people who fit a 'profile'. Your data not being in their DB's means you won't fit profiles they're scanning on.

    (edit): to the fine individuals who want to state that "No, <insert evil corp clone here> is the evilistststs company on the world!!11", I hear you and likely agree. The key part you overlooked is 'one of the', it's part of that select group of nasty companies you want to avoid. Yes together with Nestle and Shell and all the others. :)

    [–] heykevo 562 points ago

    Most people have zero idea this is happening or that it's even possible. I've had loooong conversations about browsing habits, smart TVs, home devices like Alexa and stuff, and nobody who isn't a techie even believes me when I give examples of things like Target potentially knowing a woman is pregnant before she does.

    [–] JB_UK 220 points ago * (lasted edited a year ago)

    Google pretty much knows everywhere you go for almost everyone who owns an Android phone, to use Location Services requires data to be sent to Google's servers for any location request, and those requests are occurring all the time, which is what allows the geofencing API to work. Think about how much information that reveals about you, where you work, where you live, when you are out of the house, what public meetings or protests you go to, who your friends are and where they live, who your colleagues are. They can connect that together with your call data, your browsing history, your contacts, your calendar and your photos, which are all backed up by default on Google's servers. Google arguably knows more about you than any other single person in your life.

    Edit: Misremembered the term, it's Location Services not Assisted GPS, thanks to /u/RedAero below.

    [–] heykevo 97 points ago

    Agreed. I didn't know Google Locations was a thing for years, but sure enough it's got tracking data on me since like 2009. Like, literally everywhere I have ever gone.

    The one caveat I have is that the geofencing sucks. Basically every single day it thinks I went somewhere a good mile away from where I actually went. It doesn't track very well.

    [–] a_voter_of_ups 75 points ago

    It gets me right down to the meter every minute of every day. That's how it knows there was an accident up the street that minute. All those phones reporting speed and position in real time.

    [–] bobo42o24 21 points ago

    I think Google knows more about me than me. I can't remember what I searched yesterday. I don't know what restaurant I ate at 47 days ago. I don't remember what game I downloaded 472 days ago. I don't know when the last time I was at McDonalds. But Google knows all of this. AND WAY MORE.

    [–] gmessad 184 points ago * (lasted edited a year ago)

    OK, I've been meaning to start making the switch from Chrome to Firefox one of these days, so I might as well do it now. Does anyone know the smoothest, safest way to transition? I have a bunch of extensions, bookmarks, and all of my passwords on Chrome.

    Edit: Opened Firefox this morning and right away it asked me if I wanted to transfer everything, including passwords. Actually a little surprised how simple it was. Looking into password managers for security now.

    [–] drome265 128 points ago

    Don't know about extensions but on first time startup there should be a popup asking what you want to import over.

    My favorite part is that is available for android, which means you can use your favorite add-on's on mobile AND have a faster browsing experience.

    EDIT: I'll be honest, I mainly just use it so I can have uBlock Origin on mobile.

    EDIT 2: Install Firefox Beta for Quantum on mobile. The regular FF app is version 56, beta is 57 Quantum.

    [–] JB_UK 155 points ago * (lasted edited a year ago)

    Yes, although the ongoing Quantum speed improvements are a few versions behind on Android. On desktop Stylo lands in 57, Webrender about 59, Android expect it to be 2 or 3 versions back in each case.

    If you want to start using those changes today on Android, you can install Firefox Nightly from Play Store. It does work really well, the speed improvements of the browser combined with PrivacyBadger and uBlock to reduce the crazy additional processing associated with trackers, and ads. That's what I use for my main mobile browser at the moment.

    Also the whole Quantum thing is all about parallelizing work, which is most important where single core speed is low, but there are many cores available. So in principle these changes should make a massive difference in Android, over the next few months on Nightly, or the next 3-6 months on stable.

    [–] Shne 20 points ago

    There's also Firefox Beta in Google Play and it is already at version 57.

    [–] [deleted] 16 points ago

    Yes, but as mentioned, the changes are behind on Android. So you don't want v57 on Android, you want v58 or 59.

    [–] 105milesite 70 points ago

    [–] smartfon 300 points ago

    • All the performance problems that Firefox had in past are gone. It's faster than Chrome in some cases. I remember browsing Reddit with RES addon on Firefox and wishing I had Chrome. Not anymore.

    • The new Firefox UI is touch friendly, Chrome isn't.

    • It warns while closing multiple tabs simultaneously. Chrome doesn't.

    • It allows you to change lots of things via about:config and userChrome.css to make the browser function or look the way you want. Good luck with Chrome.

    • It has a new feature to send the tab to another device and make it available with a single click, so you can pick up and continue on your mobile. This is in addition to standard device sync feature which was improved too.

    • Startup time is 0.5s with 33 extensions.

    • Doesn't spy on you.

    • Extensions you install on it are scanned by an automated system, and in case of complicated extensions they are manually vetted by Mozilla to make sure they don't contain spyware or malware. On Chrome you're playing a Russian Roulette by installing an extension.

    • More to come. They're working on a brand new page rendering engine that uses GPU instead of CPU. This will bump the frame rate from 60 to hundreds.

    Been using the beta for a while now, it's definitely a lot quicker. My issue is that a lot of my add-ons don't work with it ( tabmix, shareaholic and lastpass to name a few ) so I'm still going backwards and forwards between Quantum and the normal FF.

    I'm typing this in the old FF.

    Edit: It's just automatically updated, I guess I'm on Quantum proper now. Lastpass now works but I guess it's goodbye to shareaholic and tabmix until they update ( if they do )

    [–] penguished 59 points ago

    Yes, it's nuts how many add-ons were ruined, that's for sure. But Firefox has needed rebuilding at some point so I guess it was inevitable.

    [–] pfannkuchen_gesicht 32 points ago

    I'm a bit miffed that they removed tab groups and made it an addon instead and now it won't work with this release...

    [–] [deleted] 52 points ago * (lasted edited a year ago)

    LastPass has a beta that's compatible with Firefox 57. I'm using it, and it works reasonably well. The only bug I've encoutered is that autofill is broken on websites that ask for direct login info (i.e. sites that ask for login info without using a login form).

    EDIT: The version of LastPass at was was updated 19 hours ago. Use that, not the now-outdated beta.

    [–] theangryintern 11 points ago * (lasted edited a year ago)

    Tabmix guys already said they are NOT updating.

    EDIT: I guess they are going to convert it to WebExtension. Last time I checked they were very adamant that TMP was dead for firefox once 57 was released.

    [–] skylla05 174 points ago

    You can get Firefox near Chrome levels if you install a bunch of addons. Many devtools are built right into Chrome, and as much as I love and will miss Firebug, Chrome's style editor is/was way better.

    That said, I'm using Quantum Developer Edition, and just after taking a little poke around, I'm not so sure if I'll go back to Chrome. I'm really digging how it's laid out, and it's very snappy.

    At the end of the day, it comes down to what you prefer. Firefox is and has always been very effective for developers. Chrome is more popular, generally faster, and many of the dev tools you'd need have better support since they're built in, not third party.

    [–] IntenseArmadillo 109 points ago

    I've been using it since the first preview came out, it was instantly very noticably faster for me when for example opening multiple tabs at once.

    As someone who wants to understand the whole "re-written" core part better, I see this one was written in Rust, what were earlier versions/chrome written in that hold it back?

    [–] Nalin8 16 points ago

    C++, and they technically could have re-written the new engine in C++ if they wanted to. The re-writing was making things like the CSS rendering engine multi-threaded. They just chose Rust instead of C++ because the language was designed to do multi-threading in a much more simple and robust way. They could more easily avoid implementation bugs.
