this crash signature on windows has been around for a while but is somewhat increasing in volume since the 47 beta cycle.

[Simona Badau, Desktop QA]

I was unable to crash the latest Firefox 47 RC (Build ID: 20160604131506) with the signature affiliated to this bug - I guided my crashing attempts after the found comments from Socorro and concentrated mostly on the websites that are using Flash.

the signature disappeared with firefox 49.
