Firefox Browser rolled out beta version 96 today (v96.0b2). The UI and tabs are especially beautiful. Love it! Get the betas for desktop and mobile. I’ve never had any trouble with them.
I am also very fond of the Vivaldi browser for desktop and mobile. I get the stable releases. The snapshot (beta) releases are more beta than Firefox’s and sometimes give trouble. If you’re into testing that, all is well, but I like to stay stable with Vivaldi.
Mobiles are in the Play Store for both on Android.
