This bug was filed from the Socorro interface and is 
report bp-33d9f19c-a159-4136-83aa-160502160604.
=============================================================

Another new crash that seems to be triggered by our prompting for unsubmitted crash reports. ~230 incoming in the past week, almost all on Nightly. All in the plugin process and involving Flash. 10 occurrences in Nightly 20160603030242.

I looked at 8 or so of these, and they all had NPN_GetURLNotify or NPN_PostURLNotify.

The reports I looked at also had a ShutdownProgress value, such as profile-before-change, so I think we're trying to send an IPC message after shutdown has begun, similar to bug 1277582.

It's hard to tell without the abort message: we should really fix that to show up in plugin processes better (we can, with the new annotation infrastructure).

But given that this is rarely reported and likely shutdown, it's very low priority and I don't think we should spend time on this specifically at least until we have abort messages.

Number 7 crash in the 12-28-16 Nightly, with 17 crashes. These still are mostly shutdown crashes. 71% of the crashes in the last 7 days were on Nightly, and about 24% were on Aurora. Hopefully there's not some new regression.

#6 topcrash in Nightly 20161230030205, again with 17 crashes.

Correlations mostly show DLLs, but also indicate it's a shutdown crash.

Closing because no crashes reported for 12 weeks.
