I don't really know any real alternative if you value privacy and the openness of the web?
There are 3 companies making (as in putting the real work into it) browsers, Apple Google and Mozilla. Apple is only serving its own interests, and Google has clearly indicated where they want the web to go (more ads, less blockers, more tracking).
Ok, but you're still using firefox under the hood. Same story as the chrome reskins: you are beholden to what upstream does. You can go around limitations and do stuff differently, but pretty sure it's not the forks that will keep eg. the extension manifest V2 alive in chrome to be able to have a real ad blocker.
Firefox 124.0, See All New Features, Updates and Fixes ( www.mozilla.org )
