Dawn, hope this helps you. It works for me.

I just went to the link and followed the instructions. It is working for me when I click a tab that I have a youtube video on! It doesn't stop the sound or video for a story when I click on it in fb, but I can just mute my speaker if I need to do that. I couldn't find a reel to scroll past. lol Thanks!

Hello

To complement, Allow or block media autoplay in Firefox

For information

1 - Go to configuration editor https://support.mozilla.org/en-US/kb/about-config-editor-firefox 2 - Enter a search term autoplay

media.autoplay.default 1 this correspond to the situation Block Audio media.autoplay.default 5 this correspond to the situation Block Audio and Video media.autoplay.default 0 this correspond to the situation Allow Audio and Video

About, media.autoplay.blocking_policy, you can test 2

Version 150.0.1 in Win11 Entered about:config in address bar set media.autoplay.default to 5 Media still autoplays All extensions are disabled. Closing & reopening Firefox did not help

Hello

Allow me to ask this question, have you tested media.autoplay.blocking_policy

Anyone has a clue ?

All suggestions posted here doesn't work. Facebook is either completely rogue or Firefox doesn't respect my setting "Block audio and video".

This doesn't work either : https://support.mozilla.org/en-US/kb/block-autoplay

EDIT : seems like I have some success with : media.autoplay.blocking_policy=2 allow-muted=False media.autoplay.default=5

Hello

A similar question https://support.mozilla.org/en-US/questions/1580396

What is, allow-muted=False?

Thank you so much for your time, but this is not the problem I am having.

I just realized that these responses were for an older question I asked. I have a newer one and thought they were for that as I was confused. Sorry about that!
