Using a Firefox fork makes any difference? - eviltoast

Well, Mozilla seems to be making some pretty questionable decisions, So I’m considering switching browsers for the third (Is it the third?) time. The thing is, I really like the way Firefox works, so I’ve been trying out the more famous Forks like Waterfox and Librewolf, although I’m going for Floorp. However, I’m wondering: is using a fork enough? I mean, they are Forks maintained by other people, but is there a chance that whatever Mozilla does to Firefox could affect those Forks? Should I jump to a totally different browser like Vivaldi?
