meta: Replace firefox with librewolf

I am personally not amused by some of the defaults that firefox ships
with and would rather not have to deal with them on new configurations.
Although it's possible to sync settings across devices or simply copy
the profile directory, the advantages of librewolf outweigh the cons for
my individual use case, at least for now.
