Tablet Gestures is a Firefox extension designed to improve navigation on multi-touch screens by allowing users to perform two-finger gestures in eight directions to trigger specific actions. The supported actions include opening and closing tabs, navigating between tabs, and reloading the current tab. The default settings provide intuitive gestures, such as an 'up' gesture to open a new tab and a 'down' gesture to close the current tab, enhancing the overall browsing experience on tablets.

The extension offers customization options, allowing users to adjust the number of fingers required for gestures, as well as the distance fingers need to travel before a gesture is recognized. Users can practice their gestures using a demo page included with the installation. It's important to note that the extension is designed specifically for multi-touch screens and does not function with multi-touch trackpads.
