Browsers should probably just stop sending user-agent header at all, ideally.
If anyone else was wondering why some websites and the “Alternate Player for Twitch.tv” extension stopped working in the latest Librewolf update, it’s because they changed the userAgent string from Firefox to LibreWolf and way too much shitty code is confused by it looking like firefox but then not being firefox.
… and they’ve changed it back.
Really? If so they haven’t pushed it to the main Debian repository
According to @librewolf@chaos.social it’s still a problem in the current build if you have resist fingerprinting turned off.
Changed in 138.0-2, reverted in 138.0.1-1 which I got from repo.librewolf.net.
