Firefox is the only sane option. It’s not perfect but it’s better than the alternatives. Chromium forks are at the mercy of Google doing everything they can to stop ad blocking. Firefox forks are often maintain by just “some dude”. If they decide they don’t want to maintain it anymore, it’s done. If everyone switches to a fork and then Firefox goes away because nobody is using the browser anymore, it’s done.
