Meet Mute is a Chrome extension developed by mattsimonis that provides a convenient way to mute and unmute your Google Meet tabs. With this extension, you can easily toggle muting from anywhere using global keyboard shortcuts. The app's icon indicates whether you are currently muted or not, with different colors representing different states.

Setting up keyboard shortcuts is simple. Just right-click the app icon, go to Manage Extensions, and click on the hamburger menu to access the Keyboard Shortcuts option. From there, you can customize shortcuts for any extension, specifying whether they should work only when Chrome is in focus or globally.

Meet Mute is open source, allowing users to contribute to its development. If you have any feature requests or feedback, you can reach out to the developer on Twitter

Please note that Meet Mute is a free extension available on the Chrome platform and falls under the category of Browsers with the subcategory of Add-ons & Tools.
