- [x] Migrate functionality out of torbutton and into firefox - [x] Implement some sort of 'hook' functionality so tor-browser can do tor-specific cleanup when New Identity feature is triggered (for example, make an observer topic that can be subscribed to) - [x] Split current work done into two patches: - [x] base-browser cleanup (profile cleanup, etc) - [x] tor-browser cleanup (w/e tor-specific stuff happens ???) - [x] Ensure only depends on strings in the new localization project (see https://gitlab.torproject.org/tpo/applications/tor-browser/-/issues/40924 )
