Quiet Tabs by Stephen O'Connor

Tab Mute/Unmute All gives you a simple toolbar button to control sound across all your open tabs.

Features:
- Mute or unmute all tabs instantly with a single click.
- New tabs inherit your current mute state (if all are muted, new tabs start muted).
- Toggle icons switch between Sound On and Sound Off states.
- Minimal permissions: only uses "tabs" and "storage".
- No data collection or tracking. Everything is handled locally in your browser.

Perfect for keeping focus, avoiding sudden noise, or quickly silencing your browser without hunting for which tab is playing audio.
