This is a new feature that is not yet available in released versions of Firefox. You can try it on Firefox Beta.

Firefox lets you identify noisy tabs and mute them in a single click. Silence tabs quickly without affecting your other windows.

When sound starts playing on a webpage, Firefox lets you know where it's coming from by displaying a speaker button in the tab:

speaker tab 42

Clicking the speaker button will turn the sound off or on for that tab alone:

Mute a tab

  1. Click the speaker button to turn off the sound for that tab.
    speaker tab 42
  2. A line will appear over the button to let you know that the sound is off:
    audio off tab 42

Unmute a tab

  1. Click the speaker button again to turn the sound back on.
    tab mute 42
  2. The line over the button will disappear to let you know that the sound is on.
    audio on tab 42
Tip: To mute or unmute a tab, you can also use the Ctrl + M keyboard shortcut.
