As of today, it's a nice redesign (URL bar at the bottom!) and feels faster but its missing some features of the old negates the benefits for me: (1) add-ons, mainly for reasonable ad blocking; (2) bookmark keywords: currently they do not expand, and I use them a lot, speed is irrelevant if I need to navigate through more pages to get there; (3) (better) autofill: relies on lockwise which would be OK if not for the fact that it doesn't trigger on some websites where normal Firefox does.

Amazing! Address bar at the bottom is something strange but that makes a lot of sense: do not need to move the finger to the top of the screen to type. Nice menu and all the features I like! -- Edit since last update in June 2020 The new tab opening process is worse than the previous one! -- Edit since last update July 2020 Crashing and can't be open!

I'm so glad that Firefox is releasing a great mobile browser at last! This one is amazingly fast, it starts up very quickly and page load time is impressive. Personally I think it's faster than Chrome and Opera. Ergonomy is nice and straight to the point. Everything is at the bottom (URL, settings, tabs...) which is great as my finger is too small to reach the top of the screen. Ads/trackers are blocked. My only criticism is that I'd love to see which ads/trackers have been blocked in detail.

Seems great! I think you can still improve the feeling with a few tricks like opening the keyboard right away when we open the app. Opera touch is great for these kind of things. Also the app takes way too much space... I hope you'll be able to reduce its size! I'm confident otherwise :)

One huge problem that I have noticed is that constantly asks if you want to open a link into an App, despite the Feature being turned off to "Never" open links in Apps & all of the links cleared to not even being open into an App. I cleared all of the links last night & it still does it. But it does it on all Firefox Browsers. I browse Etsy, or AliExpress, esp AliExpress, & it asks to open the link in the App constantly. Pls send me an email for me to contact as I have found more issues. Thx

MY personal FAV browser on PC and mobile FOR YEARS to this day. All started on PC. Browser is a hod-srnd for web editing. Thought I'd try it years ago on mobile and their mobile app is just good too. It's got everything and I love the address bar at the bottom of the screen. Firefox gets it. I wish y'all would make anl sandboxed OS or even a mobile OS whete all navigation/ui controls were on the bottom of the screen like this app instead of reaching to the top corners of my screen sliding hand.

I'm not a developer, but I love this because I can permanently set it to where I can have ONLY desktop sites. All mobile versions SUCK and I can have a partial computer experience on the go! Just get a very high-end device so it won't freeze, crash constantly, nor force it to reboot like my phone does.

Downloaded this APP,as I wanted a web browser Beta-version on Android. Works really cool, but can't get an older Firefox feature to work,that allows the user to Block all images (PNG,JPEG),when visiting and downloading a webpage. I Liked Firefox for doing that, because it helps save the GB data allowance associated with my web-based browsing, when at the end of the month the data runs out.
