Mozilla plans to integrate a protective feature into Firefox 66, which will isolate the sound in autoplay.
The audio that plays automatically with a video is definitely one of the most annoying experiences users may have, especially when it's unexpected. Mozilla for this reason, starting with Firefox 66, will prevent websites from automatically playing audio.
This is a feature that already exists in Chrome from version 64 onwards. Firefox will also block media players on sites if audio playback on that site is enabled to play automatically. And it will not block anything if the media is muted.
Of course, you'll be able to set this feature through the About about: preferences # privacy page. There you have to go down to the Permissions section to enter your preferences.
“Block websites from automatically playing sound” option determines whether automatically playing media with sound is blocked or not in the program tours.
Clicking on the Exceptions button opens the list of exceptions to the rule. You can add to your list of websites that you allow to violate your setting.
Firefox users can also control the auto-play sound in the Location Info dialog box. Just click on the "i" icon next to the webpage to display options for controlling its behavior.
There you will find the new permission list “autoplay sound” (autoplay), if the website in the active tab tried to play a sound automatically.
Select "allow" to allow playback or "block" if the default setting in Firefox allows automatic audio playback.
Firefox users can block autoplay media through the permissions page about: config
- media.autoplay.blocked set it to 1 (means blocked).
- media.autoplay.enabled.user-gestures-needed set it to true.
- media.autoplay.allow-muted set it to false.
- media.autoplay.block-webaudio set it to true.
The above settings they differ from the default configuration, which simply disables autoplay of media with sound.
