That's the only reason I use FF, plus the better adblocker support over Chrome and maybe some of the advanced network privacy stuff.

Adblocker support, in chrome? Does that exist still (I use FF at home with blockers and vanila chrome without extensions at work).

Yes. They are weaker, but Manifest v3 has been tweaked a good bit since the very initial announcements, and people have figured out ways to compress old-format blocklists into Manifest v3 compatible rulesets that can remain surprisingly extensive. They are weaker than v2 blockers or Brave Shields, without a doubt, but they do still do a decent job.
