Alberto : Finally the stable release, using Quantum since 1 month and a half. Great work Mozilla, keep working for make it even better. Receive a huge hug ^^.

EpiKerCovers : Watching this video with Firefox Quantom :D

HDSQ : Goodbye chrome

Anatoly Blyudenov : Say hello to ultra ugly b&w fast peace of s... without almost all it's extensions. I have little over 60 extensions and only 9 of them (nine!!!) are compatible with FF57. FF was alive mostly because of it's extensions, because if you don't need them, why the hell you need FF when there's Chrome, which is far better in this case.

nezz0r : The upgrade itself does not look bad but truth be told I never had any design problems or speed issues with firefox and the main reason for me using this browser was: a) privacy b) addons I guess (a) does not change so that part stays fine but (b) is problematic and therefore the reason why I am not going to update my browser for some time until the addons (or alternatives) are available. For me there are three addons which are a must have: 1) Adblocker (adblock plus or ublock origin both are fine) 2) noscript [3) Cookie Monster (from s1tony: this addon was removed even before the update has happend)] As far as I know Cookie Monster will not be updated so here is a question: Does anyone know a good alternative to Cookie Monster which has nearly the same functionality?

Duck : How can I get the previous version? The only difference between the older Firefox and Firefox Quantum: Half of the extensions are not supported anymore. Bad design.

talsapps : why would I share a picture from a buzzfeed article?

Paula Benson : Used firefox for more than a decade and grown to hate it. I didn't like the last new look either except now you have obsoleted the addon I used to get rid of it (and 3/4 of all addons I use). Mozilla increasingly resembles Microsoft giving the 'customer' what it wants and not what the customer wants. Like the pocket and clip thing garbage which ought to be addons and not built in forcing me to mess with about:config to get rid them. Switched to Waterfox on PC a couple of months ago because I knew this was coming not sure how long that will last. Mozilla - you suck.

Blazeness911 : I prefer using all my add-ons than a little bit more speed.

Doogy Dog : ARGH!!!! still is crappy, cant even run YT without it crashing and huge delays. took ten seconds for each letter here.

Ken Armstrong : Looks like it's just stripped down to the skinny for tablet browsing look and feel. which I hate.

Angry RED : Nice soundtrack i loved it

eyescreamcake : "We removed all the seats, windows, dashboard and trunk, and now our car goes really fast!" - Mozilla if they made cars

teamhebi13 : Rip add ons the layout is too damn big messing up my eyes can we revert the layout to old

Abdallah Abdelazim : Really Firefox is becoming way better than Chrome

evgeny s : Firefox Quantum SUCKS ! I can't copy and paste in Youtube and Facebook comment sections. So I went back to the previous version, and it works fine.

Blazekingz : half of the addons i was using are not working anymore.....why the did it auto update something that completely changes everything.

D XD : Lots of addonos cant be used and stylish CSSs cant be used anymore. Piece of shit. The older version was much better

Shajirr : So no one is concerned that this update axed like almost all extensions, many of which will not be updated to a new version? Like TabGroups Manager for example. I can't upgrade now because it disables many essential extensions, which Firefox devs graciously provide no replacements for. Tree Style Tab is also fucked, at least the author will continue to support it.

Big_Adam_2050 : Well, time to turn off automatic updates to avoid all this.

Alex Delarge : After upgrading to 57 without knowing the extent of the changes, I've downgraded to 56. Memory usage is down and my addons work once again. 57 is, quite frankly, terrible.

desmond lau : I don't know how much better it performs on an average pc, but on an low end pc like mine, it fucked up page loading time. It's not like I have decent loading time on previous Firefox, but this quantum screws my loading time much more worse than what I had. And it loses compatibility with the older addons, which doesn't update by their dev much, I know, but ironically they are the ones that provide such variety and amazing functionality. Ultimately, loses compatibility for these addons meaning I lose my only reason to use Firefox. Sincerely. Am disappointed. The product differentiations are gone. Only one word is left, speed, but that's not prevalent in my case either. And yeah, it is now without the option to stop the page in the middle of loading. Another detail that is killing me. Utterly disappointed.

popsingerstar : this new firefox sucks

Sebastian Hahn : afaic people don't use firefox for "speed", they use it for customizability. Now that's gone, and this update installed even though I disabled firefox updates specifically because I didn't want it. I'm using waterfox now, for as long as it lasts. Thanks for killing FF Mozilla; enjoy your new ugly theme and your reduced functionality/customizability.

Mae Beyond : I like the new firefox

Evol Bob : Firefox Well its been two weeks with your new Quantum version and all I can say is...its a pile of shit. How do I know...because I've just managed to uninstall, reinstall the previous version, AND GOING BACK HAS RELEASED THE PAIN. The immediate relief I have in using this version was completely unexpected, but it has reinforced my feelings that I've done the right thing. I definitely recommend those who are just suffering and PUTTING UP with Firefox's brain fart, in forcing the layout change, with its a fucking security update reasoning. Listen up Firefox designers: Its fine to insist on the security update but...ASK if we like the new cosmetic layout changes, and the option to roll it back or say no thanks.

ITISolutions : "We've listened and redesigned our (fill in the blank) to best serve you" is what you hear or read just before your world is about to be turned upside-down. The design is counter-intuitive, the features you loved are gone, it cost more money, or any number of other possibilities that make something that you loved into something you now despise. They don't listen, they do what they think is cool, or if a company, what enhances their bottom line, without regard of what the peasant users think about it... Booooooo.

Leonardo : The best browser it is.

bored2kGER : Every update they make it worse and now most of my extensions won't work. Time to switch to something else.

Snooby66 : As I was not aware of Quantum, I was surprised to see it after an FF auto-update. Pages load 2x faster? Erm, nope. In tests I found them to load 4-5x slower. 30% less memory usage than chrome? Let's say that I have now learned about the "about:memory" tab and how to "minimise memory usage" every time it gets near to 2GB, otherwise it crashes ... once it's finished locking up my PC for 5-10 minutes, that is. Smart new interface? Well, it's a Metro interface, so it's not new, it's not smart and it's not welcome. I have returned to 56.02 and It should be no surprise that auto-update is now turned OFF.

Fuse : How do I go back ? please

Tomasz Demoncs : Hopeless, slow, incompatible. 10 or more cards and slower than FF 56 I used FF57 week and I have heartily enough.

Nick Adamski : Best browser

Offensive Username : The new design looks like a turdpile. It's like everything was thrown together randomly.

ecotts : Awesome browser, its just a shame that Mozilla includes a BBC icon as a TOP site example for their new default interface. Now considering the BBC were complicit in covering up pedophiles within their own company I think that's the last company on earth that should ever be considered as a default top site example. Oh and building 7 anyone?

Rafaelinux : It sucks, man. :<

Sulfen : I may finally switch from Chrome to Firefox permanently. I hope that they keep improving because there's still a lot of issues. On Mac it's still not as good as Safari especially with some trackpad movements. But on my Windows desktop its really good.

Cesar Alvarez : For a longer search bar at the top, open the Firefox menu, then click on ''customize'', then delete the Flexible Space toolbar.

Zistheone2 : I personally hate this new version of Firefox because it makes my computer twice as slow. Every time I open it now, it causes my computer to lag like crazy & I’m forced to shut my computer down almost all the time anymore

Kamione100 : That design is ugly as hell, i want the old design back... It's giving me cancer, even the dark theme.

برامج بوك - لتحميل البرامج والتطبيقات المجانية : بصراحة البرنامج ممتاز جدا خلاص مع السلامة يا عم جوجل كروم دي اهم المزايا الجديدة اللى تخليك تستغني عن جوجل كروم بشكل كبير خش خدلك بصه هتغير فكرتك تماما https://bramjbook.com/download-firefox-quantum-browser/

ADNAN AYUB : For android?

The Skyrim Inquisitor : My Firefox automatically updated this morning, and it's running slower than the previous one. I don't like this update at all...

Anonymous : great, now my add ons don't work

Erich Zann : I've seen many comments about the UI and breaking plugins and so-called speed, but nobody, and I mean NOBODY, is talking about the security issues. 1) Cannot easily disable Javascript; 2) Pocket is enabled & ubiquitous; 3) Mozilla spyware enabled by default (see their latest fiascos in breaking user trust); and 4) need I go on? I've been a long, long time user and have really grown to detest Mozilla as a company and Firefox as a browser. It's getting to the point where one should only use the Internet for limited reasons; if that person is concerned, at all, about privacy and/or security. I will not do my banking online, nor do I often use online shopping. I do not trust these companies to do the right thing. They are all becoming, or have been for awhile, evil. Fuck the UI, I can learn to live with whatever P.O.S. they decide their customers "want". Fuck speed, I can learn to live with a few milliseconds lag. What I cannot live without, however, is a focus on privacy and security. And in this, the new Firefox fails miserably, much more so than its predecessor.

Funcle Ron : Six Reasons Firefox Quantum Sucks Azz 1.) It disables important extensions like Roomy bookmarks. 2.) It's honestly slower than the previous version and Chrome. 3.) The dark gray bar at the top is ugly and distracting. 4.) It overheats my system when I browse image heavy sites. 5.) Bookmark drop down folders are buggy and laggy 6.) I loved the previous version of Firefox but Quantum is just unusable. Anyone else having these issues?

askeja kearf : Horrible design

ITISolutions : Thank you FF for giving us Chrome.... :( I use Chrome when I have to, but I dislike it. That's why I've been a FF user for many years now. But with 57 I feel totally betrayed. The majority of plugins I relied on don't work (don't blame them, mostly small operations develop the extensions and can't gear up for such a big change in the code) and that was an absolute BS move. Thank god for Waterfox!

megla : Works pretty fast, but the less RAM is bullshit. Currently have 14 tabs in chrome with 600 MBs used, while Firefox had 3 and it's using 1.2 GB.

TinonZR : Well I don‘t know what you have done but my PC starts lagging if I only open Firefox. Ganes which I play with 110 FPS are dropping to 6 FPS only because I‘ve opened this new Firefox. When I open it if nothing is open in the forground my CPU is at its limit and Firefox uses 60% of the capacity from my CPU. I really liked your browser but now I'll switch too something else till this bug is fixed.
