How do I backup or transfer my Firefox user profile to another computer? or What's the best way to ma

OP here—y’all are legends! Found my firefox user profile using `about:profiles` (why didn’t I know this sooner?!).

Backed it up just in case.

But now I’m curious… if I move this profile to a new PC, will *all* my extensions and settings carry over? Or just some of it? 🤔
