Nit: I would probably have merged these two if-branches and branched the first InitEvent argument. Up to you though.

Part 1 - New API without permission checks

All the code should be inside some
#ifdef B2G.
We must not expose these onfoo handlers on desktop FF.
(I wonder if you need a new interface to add onfoo handlers to window)

I think you want to pass true here in both cases as the last parameter, so that observer service doesn't
end up keeping window alive.

Actually, given that bug 758269 has landed now. Can you add the new permission to PermissionsTable.jsm rather than just permissions.txt. The permission should be ALLOW_ACTION for certified and DENY_ACTION for everything else.
(In reply to Olli Pettay [:smaug] from comment #4)
Ah, mObserver is passed to AddObserver. Then one needs to call RemoveObserver
Updated patch that prevent an assert (see bug 795703) and run-time leak.

Unfortunately, because of bug 795711, tests can't work. I forgot about that because I had a workaround locally to be able to work on the patch.
