(I've moved this from issues to discussions, because it is out of scope of TST project itself. It is a common knowledge about customizing Firefox with userChrome.css.)

The instructions worked fine for me. (LM 20.3, LibreWolf 99.0.1) Maybe you should list out exactly what you did. I don't use Linux very often, but did find it challenging to find the "Root Directory" of LibreWolf ... I couldn't find it until I read: Where do I find my librewolf.overrides.cfg?

In Firefox, simply doing about:profiles -> default profile -> Root Directory -> Open Directory works fine.
