 > What I had thought was: by default in Tor Browser we only have private
 windows, so it makes sense to always enable extensions. Otherwise from the
 user perspective it will be broken behaviour: they might install an
 extension and see no change (icons, etc.), then maybe file bugs.

 installing extensions others than the shipped ones. But, at the end of the
 day, we do not forbid installing extensions either, so this change might
 be surprising for users.

 Okay, that's not unreasonable. After all the users might not know (and
 should not need to know) that they are in a special mode. They just want
 to have a working browser and installing extensions is surely working
 without issues in a vanilla Firefox, right? Let's take your patch then. We
 can revisit that decision later on if needed. Cherry-picked onto `tor-
 browser-68.1.0esr-9.0-1` (commit
 8aabfb8128a8125a00d0a36d41518379258e0b38).
