Hi all,<p>I just got att fiber installed and I'm having trouble loading youtube videos on firefox.<p>On some videos it load no problem, on others the network activity is 0 (on stats for nerds) and it wont load at all. I've tried changing my dns, clearing cache, turning off ipv6 on the router,turning off hardware acceleration, disabling adblocker, forcing h264 and signing out.<p>The time of day doesn't seem to matter either. Videos work flawlessly on opera so I can use that but I'm curious if anyone has had this issue and possible solutions.
