I middle click to start YouTube videos and let the intro play through before changing to the new tab. How do I switch it back to where it DOES autoplay in new tab?

This one has a slightly obscure name...

(1) In a new tab, type or paste about:config in the address bar and press Enter/Return. Click the button promising to be careful or accepting the risk.

(2) In the search box above the list, type or paste autop and pause while the list is filtered

(3) Double-click the media.block-autoplay-until-in-foreground preference to switch the value from true to false

Success?

You can also check for issues caused by extensions.

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 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
