youtube does not automatically play the next video in the playlist when its loaded

When a playlist is loaded and played on YouTube, the next video in the playlist should automatically start playing once the current video reaches its end. This feature is commonly known as autoplay. However, I couldn't get it to work consistently. When the current video is finished, next video is loaded normally but where it should automatically play it doesn't.

I have tried below to address this issue:

  • Autoplay next video works in safe mode.
  • "allow audio and video" in autoplay permissions in https://support.mozilla.org/en-US/kb/block-autoplay doesn't help
  • I have also set media.block-autoplay-until-in-foreground preference to false in about:config but didn't help
  • I have tried uninstalling all extensions and it didn't help
  • Tried logging out of youtube, but this didn't seem to help with the issue.
  • Tried "Clear startup cache" in "more troubleshooting information" menu, didn't help
  • Tried "Refresh Firefox" which didn't help

Thank you.

Thank you for spending time on this issue. From what I tested it seems to work consistently in Troubleshoot Mode. When I encountered and reproduced the issue for testing the youtube web page was always active and visible with the media player in the view. However when I tested again just now in normal mode to see if I could reproduce this issue, I couldn't reproduce by playing 10 different playlists I could search on youtube. Since I changed nothing in my Firefox configuration and there was no Firefox update, I think it was youtube issue. Regards,

p.s.) and it seems I can't upvote more than one comment on the topic, sorry about that

Does it consistently works in Troubleshoot Mode?

Is the youtube playlist tab active and the window always foreground and visible?

Also make sure that the HTML5 media player is visible (i.e. you haven't scrolled down).
