Jim can you reproduce this or are you filing it from crash-stats? If you have STR I'd love to see if we can debug both this process as well as the other Flash processes, since I think the problem is likely in one of the Flash processes. This is reported as a plugin crash, but is it possible that this is a hang that's getting misreported?

Unfortunately I found this and filed off crash-stats. We just got plugin crash submission working again so I'm going to be digging into these for e10s over the next few weeks. I'll look into issues with the hang detector. Quickly poking at it we don't appear to be tagging plugin processes from the new hang monitor... I'll file a bug on that once I confirm.

We still tag with the same annotation - https://crash-stats.mozilla.com/search/?product=Firefox&version=40.0a1&plugin_hang=__true__&_facets=signature&_columns=date&_columns=signature&_columns=product&_columns=version&_columns=build_id&_columns=platform#facet-signature

Unless you have more specifics, I recommend duping this against the generic bug for this signature, bug 774281.
