=============================================================

This crash is happening on the media decoder thread. The part of the stack I could see in a crash report I looked at had a bunch of frames of this decoder thing, then some COM stuff. I don't know what Firefox code is calling into this. The URLs are various video sites, such as YouTube.

This crash is happening on 59, 60, 61, and 62, but 56% of the crashes (60, from 12 installations) are on 62.

This is the AMD VP9 decoder crashing. We've removed the decoder in Bug 1470754, and I would expect this to stop as that fix rides the trains. I'll take this to keep an eye on it and make sure the crashes die off as expected.

This is falling off as expected. Remaining crashes are in ESR, and look fairly rare. Closing for reasons discussed in comment #1.
