LeisureKit per Francesco Vito Giotta

Discover your favorite books, radio stations, TV shows, movies, and sports! This extension gives you quick access to a world of entertainment and information with just one click. Technically, this is a WebExtension using HTML, CSS, and JavaScript for its UI. It relies on a manifest.json file for permissions, and popup.html as the main interface. It's a non-persistent script, activating only when the user clicks the icon.
