You can reset these and remove them from your overrides to clear out the noise. ⭐ 136 is already out (don't ever wait on arkenfox to update your Firefox). The new FF136 prefs will migrate from the FF128 prefs which migrated from the legacy prefs. **_It pays to open each dialog to ensure the migration happens._** Update any overrides to suit. Note: the migration happens _after_ the user.js is applied.
