Many Linux distributions offer no ready way to inform users of available extensions, or direct users to the extensions. In order to view the available Gnome Shell extensions, log into your machine using the Gnome interface and fire up your favorite browser. Head over to https://extensions.gnome.org. You should returned with an interface similar to what is shown here.

Note

Your browser will need a plug-in to handle the links at the Gnome extensions site. If you have Gnome Shell installed, it is likely you already have the right plug-ins.
