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.

Pros:

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

Cons:

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

You can change to use the address bar as a search engine and get rid of that search box on the right in Preferences > Search. I'm not sure about your other concern but I think it's fantastic.

If you right click the tool/search bar section, firefox included whitespace "icons" you can remove that will fix the issue you have with the blank space around the search bar.

@dorelljames, @hingadingaling thanks a lot, so the concern about the white space is out and the ability to customize these icons makes it even better. After several more days of use, if I exclude the rendering issues (which might as well be websites' compatibility issues, not browsers') it feels great.

HEALTHY IS MANDATORY Hello Friends, The information you share is very interesting. I want more information from you,Thank you

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!

Pros:

It is faster than ever.

Cons:

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

That's the reason I don't use Chrome, even though it's speedier than Safari. It's an absolute resource hog. Looking forward to having a speedier alternative to Safari now!

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.

Pros:

Memory Usage, Privacy, Speed, UI

Cons:

Very rare render bugs.

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!

Pros:

UI, Speed

Cons:

None

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.

Pros:

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!

Cons:

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.

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.

Pros:

Looks nice in the video, potential is there

Cons:

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.

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.

Pros:

UI, Speed, Feature Packed

Cons:

None yet

Currently using Opera as my default browser, but will switch to Firefox Quantum when it'll be fully released.

Pros:

Fast as Sonic the Hedgehog, doesn't take my whole RAM to launch

Cons:

Nope

Founder @ noo.coffee

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

Pros:

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

Cons:

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.

Always distracted by new shiny things

Initial impressions are good but I will not be switching browsers just to do video calls when remote from the office :(

Pros:

Feels quick, looks good

Cons:

Not Firefox's fault but no Google Hangouts working

I joined Mozilla 9 months ago and this product is a big part of why.

Pros:

Fast, open, private, secure

Cons:

Could use some more operating-system-level integrations

Always be strong

I usually use Google Chrome, but having wayched the video, I've decided to to start using Firefox

Pros:

It is really fast

Cons:

I haven't found any

Great, can't wait for version 58!

Pros:

Snappy fast

Cons:

Tabs squash too thin

have replaced all chrome usage with firefox developer edition!

Pros:

Fast and low footprint

Cons:

Extension support < Chrome

It's not all about how fast and how much memory and etc... it's all about the ecosystem. It's really hard to win the browser war now.

Pros:

Fast and open source

Cons:

Dev tools are not up to google chrome standard

Overachiever since tomorrow, Hunter

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.

Pros:

Speed, Design & other built-in Tweaks

Cons:

Buggy sometimes

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! :)

Pros:

Speed & UI

Cons:

None so far

Smile everyday :)

Since I used Firefox Quantum, I got A+ in school :)

Pros:

Quantum engine!

Cons:

Fast!

And Photon UI is pretty.

It has all the features a modern browser should need. I haven't delved into the Dev Kit, yet, so that's an area I'm not sure on.

Pros:

Fast; good UI; syncs well; customizable; screenshot editor; privacy options

Cons:

Add-ons are limited because new update required apps to update. Shouldn't be a problem over time.

I would like to see more add-ons coming from chrome web store natively

Pros:

Fast, Open Internet, Privacy

Cons:

Implement more add-ons
