report bp-c9d5d223-cec4-43da-847a-8a4360170620.
=============================================================

I just got this crash when switching tabs to the (already loaded) Gmail tab. First time in a week that I am getting a crash at all while running with E10S and the Handler on.

handler related, I think we just turned this back on today. Low volume so far but that will probably change. The crashes are off the main thread in RPC land. We should triage this at the next meeting.

Attachment: Use IID instead of REFIID to store handler's target interface id

The REFIID had gone bad, hence the crashes. Replacing with IID so that HandlerProvider stores its own copy.
