New description:

 Despite setting browser.cache.offline.enable to false, we still get
 prompted for allowing offline storage when sites try to use it. Canonical
 example: http://html5demos.com/offlineapp

 The prompt appears to be governed by browser.offline-apps.notify, which we
 don't set.

 I am pretty sure that this prompt runs through the permissions service,
 which we make memory only (#2950), but we should double check that through
 direct test.

Comment:

 We should disable this entirely. Users should not be prompted to enable it
 until we support it.
