Hello all,

I am having problems with video playback on some websites (see screenshot attached). The problem is that the video options start to "multiply" - for example, when I start the video there is (as is normal) one 'Speed' and one 'Quality' button, but then every second these buttons start to multiply. This happens only on some websites - for example, it does not happen with normal videos on YouTube, although it happens on YouTube Shorts sometimes.

This is my first question on the Mozilla Support page, I thank you in advance for your help and I hope I follow the community guidelines. Please feel free to leave any suggestions or feedback concerning how I should proceed for asking for help in the future.

Start Firefox in Troubleshoot Mode to check if one of the extensions ("3-bar" menu button or Tools -> Add-ons -> Extensions) or if hardware acceleration or if userChrome.css/userContent.css is causing the problem.

  • switch to the Default System theme: "3-bar" menu button or Tools -> Add-ons -> Themes
  • do NOT click the "Refresh Firefox" button on the Troubleshoot Mode start window
