While watching videos on YouTube, playback occasionally stops on its own. I am aware that the website has a feature that stops playback after 15 minutes of inactivity, but this seems to be a different issue.

In addition, videos sometimes stop playing when I switch to another browser tab. In those cases, playback resumes as soon as I return to the YouTube tab. The behavior is somewhat similar to the YouTube mobile app, where playback may stop when the screen or app is switched.

Both issues tend to occur near the beginning of a video rather than throughout the entire playback session.

I did not experience these problems while the add-on was disabled, so I suspect there may be some compatibility issue between the add-on and a web service or browser feature.
