Mute sound in Firefox tabs
Firefox lets you identify noisy tabs and mute them in a single click. Silence tabs quickly without affecting your other tabs or 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:
Clicking the speaker button will turn the sound off or on for that tab alone:
Mute a tab
- Click the speaker button to turn off the sound for that tab.
- A line will appear over the button to let you know that the sound is off:
Unmute a tab
- Click the speaker button again to turn the sound back on.
- The line over the button will disappear to let you know that the sound is on.
