Yes, Librewolf is basically Arkenfox. I made a project fixing Arkenfox for me.

It is probably not that well maintained and the general arkenfox stuff is not easy to deal with it, very overcomplex.

But basically you want to keep track of the updates but still override the things you like.

So arkenfox sucks in many ways, it is extremely "I hate mozilla" opinionated to a level where version update "whats new" dialogs are completely impossible. I would highly prefer a compartimentalized set of settings, but maintenance is hard.
