I am looking for alternative knowledge sources to mozillazine that’s a bit more up to date.

Specifically, I am after something that explains advanced about:config options and what each sqlite file and storage directories in my profile are actually used for. When I search online for things I get unhelpful support articles from mozilla and random reddit threads with conflicting information.

I’ve played around with a lot of things through a lot of trial and error (I can share some about:config values if anyone’s interested in them), but I’d like to be directed somewhere I can go to and check to make sure I won’t break my profile.

I already use ffprofile to set up my user.js, but I’m looking for something with more documentation without having to resort to reading the source code of firefox.
