Presence is a proposed Cloud Service that tracks a Firefox OS device's Internet connectivity status as ''online'', ''offline'' or ''unavailable'' by the device's Firefox Account. A Firefox OS Web App may request permission on behalf of its publisher to read status. Once approved, the publisher may poll the Presence service and, once the device is back online, push messages to the Web App.
