This bug was filed from the Socorro interface and is 
report bp-ce1b6d6d-1699-4976-99b3-82f362151019.
=============================================================

Seems we didn't cover all the cases in bug 1195998, as there are crashes in version 44 (multiple platforms, see also https://crash-stats.mozilla.com/report/index/c7b1930f-7244-4890-9900-6bff72151020)

:nical, can you or Bas take a look at this, so that we're not left with the partial fix to ForceRemove crashes.  Let's focus on the IPC related crashes.

This is clearly a case of the textures kept alive until too late in the shutdown.
I spent some time looking into the media code and it looks like most of media is at least intended to shut down synchronously during when XPCOM_SHUTDOWN_OBSERVER_ID is fired which is what we need, so my current hunch is that maybe the plugin code doesn't get shut down in time. Digging...

No sign of this crash in 45 and 46 where bug 1207220 is fixed (44 uplift on the way). So marking as fixed, don't hesitate to reopen if it happens again on nightly or aurora.

Apparently, one of the signatures from bug 1243765 causing trouble in 44 release matches this bug.

Bug 1261347 which just made it to mozilla-inbound should fix this.

It would appear that bug 1261347 never landed but the volume of this crash is extremely small now.

Feb 1: ~205 crashes/day

Looking at recent crash reports it's all in Firefox 44 or earlier. I can't find any recent reports with a build we currently support. I don't know exactly what fixed this so I'm going to call this WORKSFORME. Feel free to reopen if there's evidence to suggest this is still an issue with current Firefox builds.
