    Speed; UI; Sync; Ability to do page screenshots;


    Found several websites which work great on Chrome but have issues with Firefox;

    Have been using it for some time now and migrated everything from Chrome. The Firefox Quantum features a great speed improvement, indeed, and a sleek new UI. (Look at the update below). However, I don't really like that the address and the search bar aren't taking the whole empty space but are rather constricted in the center of the toolbar. This creates some awkward blank space around them and on the right side, it feels like there are several missing toolbar icons. Everything else I've seen about the UI feels great, especially the tabs, the colors and how unobtrusive the new UI is in the browsing experience.

    Update: As others have pointed out in the comments, the whitespace around the toobar could be removed and the toolbar icons can be customized so this is not an issue.

    It might be me, but I have also observed some issues with pages rendering (the Firefox install I'm currently running is clean from ad-blockers and such plugins). For example, when I open a startup page on BetaList, the main image is never loaded. It might also be a compatibility issue of this particular websites.

    I especially like the sync feature and the ability to easily make page (or element) screenshots directly within the browser and without looking for thrid-party extensions.

    It is faster than ever.


    I am not sure I am into the whole "integrating external services intro the browser".

    I have used firefox almost exclusively. Fooled around with chrome for some time but I wasn't happy with the memory usage on my machine. The only thing I missed in firefox was the speed. Chrome used to perform better than firefox but that has changed now!

    Memory Usage, Privacy, Speed, UI


    Very rare render bugs.

    I've been playing with Nightly on and off for the past 6 months and I switched to Firefox Developer Edition as my daily driver whenever it switched over to using the new engine (~2 months ago) just to "try it out".

    Two months later and I'm still "trying it out"! It's really that good. It is just a slight but very noticible speed increase and knowing that I'm not giving google allll my data without a bit of a struggle that makes me strongly reccomend it to anyone who will listen.

    UI, Speed



    Been using the Quantum version (now FF 57) for a while and I am really impressed with its performance and polished UI. The webpages rendereing must more quicker than the old versions, scrolling is smoother and the Chrome takes less space, giving more to the web page. This is definitely a great release for Firefox and I am sure more improvement to follow. Onwards and upwards!

    Love how Mozilla did a complete 180 on Firefox. Funny how I jumped from Firefox to Chrome... and now it seems like I'm ready to breakup with Chrome, and go back to Firefox.

    Super fast browsing engine, fresh UI and forward thinking devtools. Firefox feels relevant again.


    Still a tiny bit rough around the edges for web dev work.

    I've been using Firefox 57 since it hit Nightly, and good god was I impressed. The difference against 56 even is like night and day. My friends used to always tell me to use FF over Chrome, but it hasn't felt like a real contender until now. I now use Developer Edition (58 beta) as my main browser for front-end dev at work, and I can say it's only going to get better from here.

    Buggy sometimes

    Absolutely loving it since Beta. Just updated to stable build released today. Might switch to Quantum completely soon if updates keep making it better.

    As someone who constantly keeps killing my Tabagotchi with dozens of open tabs, Still not a fan of the scrolling tabs feature of FF.

    Very rare page render issues (to the point of having to use Chrome)

    I have used it since Beta and it has stadily become my standard browser (again). It is more or less just as good as Chrome, but with SO much better team and philosophy behind it. I don't trust Google anywhere near as much as I trust Mozilla and the gang. I have just waited for a good enough Firefox to be able to give my support again (and not just in terms of donations).

    Firefox quantum is insanely fast. I have never experienced a faster browser.


    Chrome offers a much more robust extension library, but apparently Foxified solves this.

    Firefox Quantum is sleek, modern, and absolutley the fastest browser I have ever used. I am not one to abandon the products I love, but I ditched Chrome after about 3 minutes of use and have no plans on returning. Worth a download.

    Nice UI layout, better tech


    Locks up, faster render pipeline useless if UI becomes unresponsive

    So I excitedly downloaded and installed this on my MacBook Air and closed Chrome.

    I immediately went to TheVerge (One of the most media rich sites I could think of) to test the purported speed increase and the entire browser locked up for 1-2 seconds..."weird' I thought and began to scroll...it locks up again.

    I tried several basic sites like OSNews and LXer (Very media light sites) and got the same result. Whats going on?

    None so far

    Have been using Firefox Nightly for some time now, and so happy to get a stable release of Firefox Quantum - my favorite browser got completely revamped and built from the ground up. Thanks, team Mozilla! :)

    Finally got me back off Chrome!


    Hopefully this will re-ignite add-ons for Firefox but some of my fave Chrome ones are missing still, i.e. Panda

    Love it love it love it, in a world of data using tools by certain companies worry me more and more, yet I still use them for their supremacy. I am a huge fan of the work Mozilla Foundation do and I am glad to finally be a Firefox user again, after 10 years or so of Chrome.

    Fast UI and page rendering


    Some applications like Hangouts don't work

    I've been using FFQ for a week, and the experience so far has been

    great. I have the usual plugins/extensions installed: an ad blocker,

    LastPass and Vimium.

  • Pros:ย 

    Low Memory Profile, Fast, Sync, Readability, Privacy


    Missing Chrome's omnibar features, no built in pass generator

    I switched back to FF for two reasons. First, Chromium, in my case, has severe memory leaks, consuming 16GB RAM and not releasing it even with all tabs closed. Second, because of the web. Having a powerfull Mozilla is good for the web and its standards (DRM's case comes to mind.)

    I don't like anything absolutely


    Now it's a raw alpha version without optimization.

    One of my computers built on the platform x86 and Core2Duo. I have endless crash on new FFQ. Crash, crash and crash. Over and over and over again. Opening pages are really slowly compared with
    old FF. Don't use this browser on old or weak computers. Support Mozilla did not respond to my complaints.

    Sooo... Non-usable now. I'm waiting for optimization updates and i have to use Chromium now. New Firefox is really raw.

    How to downgrade to old FF and how to disable automatic upgrade to new FF?

    Looks nice in the video, potential is there


    It broke everything I liked about firefox: I've customized to the nth degree and not one of my extensions worked with quantum, ugly ugly.

    Maybe in two or three versions it will work, but right now, it's better as an idea than as a browser to use every day.

    It's fierce and fast. Always the Firefox that I wanted and the new Screenshots tool has made it even better. I should say I love it now!


    It's reported by a few that Firefox Quantum is using a lot of memory. I don't speak on the tech front, but this could be changed if true.

    Firefox Quantum is always the Firefox I wanted. I wish more people adopt it and support the open-source drive Mozilla has always infused in us.

    Blazingly fast. Beautiful UI. Pocket integration. Mozilla's ethos.


    Lost custom styling during update but fixed quickly. Most add ons didn't update even though there was an update available for most of them.

    Overall really impressed with this product, no reason for me to use any other browser now.
