Alberto Díaz López : 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 ^^.

HDSQ : Goodbye chrome

EpiKerCovers : Watching this video with Firefox Quantom :D

Abdallah Abdelazim : Really Firefox is becoming way better than Chrome

Fuse : How do I go back ? please

ADNAN AYUB : For android?

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?

Mae Beyond : I like the new firefox

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.

Leonardo : The best browser it is.

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

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.

Nick Adamski : Best browser

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.

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.

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

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.

Chef Truong : love it

Toni Rocha : Squared tabs? oÔ'

Angry RED : Nice soundtrack i loved it

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.

ki hyeok Jang : I am using nigtly and It is the best browser Ive used

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

FileHorse : New Firefox is Amazing! <3

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

Fx : Why are comments disabled on most of these videos?. Comments and replies to them would have made a lot of those videos much more popular due to activity on them and probably in turn helped to boost the popularity of Firefox too. It's very Apple like controlled walled garden behaviour from a product which is supposed to be synonymous with being free and open.

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

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

Yowan Rdotexe : But does it support hardware accelerated video decoding on Linux using VA-API/VDPAU? Or are we still stuck with cpu decoding?

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

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

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.

askeja kearf : Horrible design

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.

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?

eddy haze : all my saved folders turned black and white , I don't see a way to turn it back

Sonic The Coolest Hedgehog : Way better than Chrome, Whenever I use it it's so damn laggy AND it keeps Kicking me off. So, I'd prefer Mozilla FireFox over Chrome Any Day.

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

連李 : watching this using the auto update turned off version of firefox 56.0.2 :DD

James King : Firefox quantum much faster than the speed of light...Hell yeah!!

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

HeroX : chrome > Firefox

Jurij Fedorov : Uses 32% less ram than Chrome? This is hardly a brading point as this still means it's an extreme memory hog.

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

WallyWinka : I don't like it. Not only was I not given the choice to update or not, but now that quantum has raped my computer, most of my addons/extensions don't work any more. Not to mention that it just looks like CRAP with it's ugly simplistic line-art icons that have been scattered over the top bar, crude sharp corners on the tabs instead of the curved flowing edges like before, and just overall CHEAP, crappy look as if a child designed it in MS Paint.

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

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

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.

Spinach Daily : 👍

What's Trendz : Wow Keep it up Mozilla!!!
