AdNauseam doesn't work

conflict in about:config?

I have a similar issue. It blocks the ads but doesn't open them.

Unsure why it wouldn't work unless it's an about:config conflict.

Edit: by "no internet" do you mean you can't access any website?

Edit2: may want to check out here, granted it is not librewolf outright, may have some useful nuggets to try to help.
