Ratings and reviews

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.

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.
