Are you tired of searching for the typical browsing buttons (back, forward, reload, close tab, etc)? Don't worry, you don't even need them anymore.
easyGestures is an extension for Firefox that lets you keep your browser's most common action buttons always on hand.
Simply click using your mouse's middle button or wheel anywhere to see an intuitive pie menu containing the browser's main action buttons.
