Last I checked, LibreWolf also wasn't on Android. I use IronFox on e/OS

(I bought a Fairphone 4 through Murena a few years back as my first foray into custom ROMs. Still debating what I will do for my next phone when the time finally comes. I do not need to be told about the concerns about Murena, that is already factored into my indecisiveness about my next phone.)
