Ok, what #browser alternatives are out there?

currently I'm using #Firefox (despite Mozilla), but it is slow and seems to go down the AI drain.

#Chrome is out (don't need even worse spyware).

My requirements would be
- (Arch)Linux, Windows is optional
- Fast rendering
- Working AdBlocker!
- No phoning home
- Not run by racist/transphobic assholes!
- Regular security updates

Am I looking for Unobtainium here?
