I cannot stop autoplay of audio/video on numerous sites despite setting permission to block all. Also tried several extensions. This seemed to have happened a couple if updates ago. Currently using 88.0.1

You can look at these prefs on the the about:config page to see what settings work for you to block autoplay.

  • media.autoplay.default = 5 [0:allow;1:blockAudible;2:Prompt;5:blockAll]
  • media.autoplay.blocking_policy = 2
  • media.autoplay.allow-extension-background-pages = false
  • media.autoplay.block-event.enabled = true

You can open the about:config page via the location/address bar. You can accept the warning and click "I accept the risk!" to continue.

Thanks for the info. Unfortunately, that did not work. The problem seems to be with specific sites that somehow are overriding these settings. Guess I just won't use them anymore.
