About this extension
This Firefox add-on shows an icon in the tab of each tab currently playing an HTML5 video or audio. Clicking on the icon mutes the videos/audio.
It also shows an icon when a plugin (such as Flash) is active on a page, because there's no way to tell if a plugin is making noise.
This add-on will not be maintained post-Firefox 42, which includes very similar functionality.
