Allow or block media autoplay in Firefox

This feature is planned for a future Firefox release. It's being tested in studies and in Nightly (pre-release) versions of Firefox.

Firefox blocks all media with sound from playing automatically. If you want a website to automatically play media, you can give it permission by following one of the methods below.

Notification prompts

When a website tries to play media automatically, Firefox will alert you by showing a message. Choose Allow or Don’t Allow to let Firefox remember the permission setting for this website. If you uncheck Remember this decision, Firefox will remember the setting for this website in the current tab only.

Click the Site Info button in the address bar to open the Control Center, where you can clear the permission so that Firefox no longer remembers the setting.
