On the Youtube page, clicking a link causes the video to load twice, except the first video select when I first open the page.

Hello. If a youtube video is embedded in a site other than the Youtube home page, video playback is as expected. Playback is correct on the Youtube site when using Chrome. I am using Firefox version 64 on a Windows 10 Desktop. This situation has gone on for approx one year, through various firefox upgrades. Thank you for your assistance.

Did you check for issues caused by an extension?


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

  • switch to the DEFAULT theme: "3-bar" menu button or Tools -> Add-ons -> Appearance
  • do NOT click the "Refresh Firefox" button on the Safe Mode start window
