Mute Tab от Balvin

This browser extension provides control over muting, unmuting, and closing noisy tabs. When a tab is muted, it can still play video and audio streams silently, ensuring that unexpected noises from browser tabs, particularly ads and banners, don't interrupt your work. This feature is especially useful during meetings or online conferences. You can mute or unmute tabs with just one click. It uses a nonpersistent background script, which means it doesn't consume any resources unless actively used by the user.

Key Features:
1. Mute individual tabs
2. Mute other tabs in the current window
3. Mute tabs in other windows
4. Mute all tabs except the active one
5. Mute all incognito tabs
6. Monitor and mute newly opened tabs
7. Support dark mode (dark theme)
8. Focus Mode (stop muting the current tab and mute all others)
This extension allows you to toggle the muting state of the currently active tab, tabs in the current window, tabs in other windows, and all tabs except the active one. You can mute and unmute specific noisy tabs or enforce the muting state for all matching tabs. Additionally, you can close other noisy tabs using a single keyboard shortcut.

You can access the extension's controls either through the toolbar popup or by setting custom keyboard shortcuts, based on your preference. User-defined keyboard shortcuts provide access to all supported actions for muting and unmuting tabs.

Please note that this extension does not support custom rules for muting specific hostnames, as this functionality is already available in your browser and doesn't require duplication.
