For what it's worth, Privacy Badger is currently one of the top recommended add-ons for me in Firefox for Android. I just installed it and it seems to work fine.
So someone has updated me in this thread somewhere that Mozilla has backtracked on their solid "recommended extensions program" and begun to work towards implementing more. I'm glad to see that, for the sake of those who will continue to use Firefox. I won't, because the trust is gone for me at this point.
