@EposVox i enjoy librewolf a lot and it seems like the best of the bunch, next to maybe mullvad's new browser which lives in a similar space with a similar source (both being firefox forks with defaults that are private but also don't reduce usability on the web).
one thing to watch out with librewolf though is that by default it trashes history and cookies with each exit of the browser, and most people probably want to turn that off.
