Ungoogled Chromium for Chrome, and either LibreWolf or Zen/Floorp for Firefox.
I'd be surprised if there were any objections to this aside from the site breakage on the latter first, which I understand completely.

Oh dude, floorp is nice but it phones home to mozilla as soon as you launch it. They never removed it
I dont know about librewolf. Any Firefox browser should not be trusted.
Does it? That's a shame then, especially since it looked to be doing a lot than Mozilla ever did (or will) on the browser then.
Ah well, LibreWolf and Zen then.
