Youtube block autoplay not working

more options

Hello,

Recently Firefox tends to start autoplaying a YouTube video if I am on the tab.

Before it would not play the video if i am on the tab unless I physically press play.

It still works if I open a YouTube video in a tab that is not active, it will not autoplay, but as soon as I hover over and click on that tab it will start playing, however I do not want this to happen, I want it to pretty much always be autoplay blocked regardless if tab is active or not and I want to physically press play in order for it to start.

How to revert it to that state?

My block audio and video setting in firefox is already turned on, not sure what to do, pretty sure I did nothing on my end.

Right now I have to use extension called "disable autoplay" just to get by.

Thanks guys!

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

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

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.

Did you check you settings in youtube in playback & performance? Not sure if this will help but worth a shot. This latest update has been a nightmare all around I see. I lost my ability to print and no matter what I do, it doesn't solve it.

In chrome it works perfect, was there a firefox update that broke this? Or was it a youtube update?

Beast!

This one fixed it "media.autoplay.blocking_policy = 2 "

Do you know how to make it so YouTube remembers where I left off it seems to have stopped saving where I left a video off...

New youtube tabs should not autoplay like you describe if you are blocking audio & video with no other changes.

You need to be logged in to a youtube account with history enabled and it only works for longer videos that you have watched for a while.

Test in Troubleshoot Mode to rule out interference from extensions.
