Mozilla has announced that Firefox 66
will automatically block audible audio and video initiated by autoplay media on websites. As this is the default behavior for Firefox 66, users will have to interact with the website to initiate the audio such as hitting the "Play" button. Firefox users will be able to override this behavior by clicking on an icon in the URL bar and changing the settings for individual websites. Firefox for Android will incorporate the same behavior as the desktop version. Firefox 66 has a scheduled release date of March 19, 2019.
