I’ve gone between a few but on desktop it’s Librewolf. Just like Firefox but more privacy by default. On Android I’ve tried Fennec, Brave, Iceraven, and Mull. Out of all of them Iceraven has been my favorite simply because of its support for desktop extensions.
Glad you mentioned that! I found out about it a while back. It’s nice but Iceraven having it out of the box no hassles is nice.
