Well, I would extend FF to all derivative browsers, particularly those oriented to privacy, like Librewolf on the desktop and Mull on Android. Their in essence their FF counterparts with privacy settings applied, and removing binary blobs (yes FF still include some)… But I guess those are even less known than FF itself, :(, though overall, they depend on FF being maintained and progressing, since those projects don’t develop a browser one their own…

firefox on mobile cant have more than one tab open at a time, ill use brave thanks
