So yea I've noticed opened Youtube tabs will just randomly start the video playing while I'm in another tab, it's really annoying. I've tried disabling all extensions but it continues to happen. Anyone know whats going on, it's been happening for a really long time.

Using Windows 11 Firefox version 133.0.

The default Block Audio setting will prevent autoplay for all media with sound. The Block Audio and Video setting will prevent autoplay for all media, including video, even though audio is muted. The Allow Audio and Video setting will allow all media to autoplay.

Beim Spielen Udemy-Videoclips kommt es bei manchen Teilen zu WidevineCdm-Plugin Absturz und Videoclip kann nicht bespielt werden. Was soll ich machen um diesen Fehler zu beheben?

When I navigate to a YouTube video, I get the word YouTube in giant font as shown in the attached screenshot. There is some gibberish along the left edge. Actually, when I navigate to a specific YouTube video, I watch the correct video show up normally for about 1/2 of a second and then it immediately converts to the attached screenshot.

 This does not happen with Safari, and it just suddenly started happening today with Firefox. My guess is that a setting suddenly got changed by accident. But there may have been an upgrade that does not work on my computer. 
 Any suggestions or ideas for further troubleshooting would be welcome.
