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.
Ublock origin blacklisted trackers list might not be exhaustive so privacy badger will pick up.
Btw I’d love to have a nice explanation on how it works if you think I’m wrong
