Ratings and reviews

Thee best browser currently available. do not like telemetry though xD. I I use about 10 add one or more (all Webrtc and Canvas blockers, privacy badger etc ). it doesn't consume tons of system resources like other browsers on both mobile and Windows. This was an issue with other browsers like brave, edge, opera, and the whole lot. I tried all the Firefox browsers and this one continues to be my go to and I am extremely picky and knowledgeable about browser functionality. This is thee one!

One of the best mobile browsers I've ever used due to the ability to freely add extensions. However, with the latest update, the search query shows up in the url bar instead of the actual url, which looks strange and doesn't let me easily know if the url I'm at is correct until the page loads/I restart the app/I copy and paste with Share, and renders copying/editing DDG !bang site links difficult. I've never seen another browser do this and it irks me. In DIRE need of a better colour picker.

About as useful as mobile browsers can get, starting with much of the security of desktop Firefox (effectively a built-in ad blocker plus uBlock), and a selection of extensions (though not all of them) which help a lot with accessibility. It integrates smoothly with desktop Firefox and works surprisingly well with sites like YouTube.
