strict mode + rpTop

checked toggling strict mode via UI changes this, also my FF100+AF has it modified true, so that means it's also runtime + ETP mode switching via user.js friendly (default is false)

FYI: the next one coming up is `privacy.query_stripping.enabled` (probably FF102, but pref added in FF101)
