 I agree with the situation being not optimal but I think those prefs
 should not get added to Torbutton. Rather, we should rip out the
 respective Torbutton functions (both
 `torbutton_update_fingerprinting_prefs()` and
 `torbutton_update_isolation_prefs()`) as fingerprinting and linkability
 defenses are not optional. We don't expose those options in the browser UI
 either anymore. I've opened #28746 for that (and #28745 for the parent
 ticket covering the Torbutton clean-up).
