LibreWolf is pretty good on privacy. Seems like it and Brave are checking the most boxes (besides Tor) per this side-by-side comparison.

Looks like LibreWolf has gone a little woke, though. I don't care about some developer's political views. But, I have a hard time using someone's product if they hate people like me.
