I was under the impression that Privacy Badger wasn’t considered useful any more . . . ? They should’ve just recommended using Firefox instead, yes?
EDIT: They spoke to, but IMHO, did not give enough time to, Cory Doctorow and Brewster Kahle. They mentioned Mastodon 👍, and described the Fediverse while not actually calling it that! A bit frustrating.
This is the GitHub repo wiki you are referring to, hopefully helps others declutter their extensions.

Nice! Stared it this time.
