Unlike Google Chrome – it’s quite easy to disable autoplay videos in Firefox.
The functionality is built right into Firefox- meaning no third-party extensions required.
While it’s not absolutely perfect – it’s a whole lot better than Google Chrome’s failed attempt to block autoplay videos.
- In the address bar enter about:config and hit enter
- In the search box, enter media.autoplay.enabled
- Double-click on the setting to change the value to false
