Mute sound in Waterfox tabs - Waterfox Support

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

Mute or unmute tabs

When sound starts playing while you’re browing, Waterfox lets you know where it’s coming from by displaying a speaker button on the noisy tab. Click the speaker to turn the sound off or on for that tab alone.

Keyboard shortcut: To mute or unmute a tab without a mouse, you can also press Ctrl + M while on the tab.
