This is the same box as the one in Bug 91083, and is running with the
additional trap-prevention patch in bug 91083 comment 6.
One advantage of firefox 40 being less stable, is it seems easier to reproduce
crashes(!) Opening a new bug, as I see the crash with the other bug's patch,
which I think was meant to reduce traps. (I also removed the NetBSD work
around)
(This was just clicking on a tab in firefox - nothing to do with video
playback)
