 Right. (See also #25587). I'm concerned about two situations regarding
 distributing updates.

 1) We need alternatives for the app marketplaces. This may mean
 distributing the app as a download from our website along with the desktop
 downloads.
 2) I don't think using the Firefox updater is a crazy idea (if the app was
 downloaded directly from torproject.org and not installed from a
 marketplace), but as far as I know this is not well supported or tested by
 Mozilla - so we may experience bugs if we use it.

 Mozilla (will be) shipping OTA updates for system add-ons on fennec (from
 what I've seen), but I don't know if that is different from full fennec
 updates.
