How do i disable autoplay on all websites - even for muted videos?

I can't disable it for all websites by default - i have to set-up individually for each website. It seems that these settings are stored in cookies, because after clearing cookies i have to set it up again.

You can look at media.autoplay prefs on the about:config page to see if these values 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.
