Yesterday (19/08/2023) everything worked fine. Today (20/08/2023) I can no longer login to Twitch using Firefox. I restarted browser and cleared cache. No change.
EDIT: I tried again after 30min and it works again. I have some privacy-oriented plugins but I don’t play with custom useragent.

I was unaware of that change, even their website still promote heuristics.
That being said, it’s not the same list as uBlock origin so you might have trackers going through ublock origin blocked by privacy badger or the opposite.
My point is, why not use both ?
Because it makes your fingerprint more unique
uBlock filters already covers everything privacy badger blocks. It’s better to have less extensions then more. More code that can cause security issues, which is why local learning was disabled in the first place. More is not always better.
