I have been using mull browser for around 1 week now. I felt like mull browser is funtastic without those firefox garbages. Also the tracker blocking is at maximum. Usually firefox have strong tracking protection than any other browser like brave, vivaldi, edge, etc. None of my usual visiting webites got blocked/breaked at all.
I only have to use localcdn and ublock origin in this browser. It’s faster than official firefox but lesser than chromium but it’s ok.
Site isolation is a matter tho. But anyway i hate chromium. Chromium and it’s forks have more reasons to be get hated.
