Recently I’ve been unable to play YouTube videos on Firefox: “Video unavailable.” I’ve tried clearing the cache and cookies, and restarting Firefox in safe mode. I’ve disabled “Use recommended performance settings” and “Use hardware acceleration.” Still no videos. I’m using a VPN and have several Ff extensions - none of them video related. The problem seemed to start after the most recent Firefox update. YouTube works fine in Safari. Thoughts? Mac mini MacOS Sequoia 15.7.4 Firefox 148.0
