The Librewolf project appears to be the best of all! I will try it.

edit: Statement below is incorrect, Brave is a Chromium fork.

I do note that Brave, Tor, and Librewolf are forks of Firefox. This in my opinion is an additional reason to support Firefox. Everyone else appears to be plundering naive users' browser telemetry.
