Comment # 3 on bug 905665 from Wolfgang Rosenauer

The patch as mentioned in the initial comment does not apply since you are
saying it's Flash what is crashing.
The upstream bug is about VP9.
What is your exact hardware? Does it have SSE* support? Which CPU?

Could be similar to bug 906561.
Please clarify what and where Firefox is crashing first and tell us your
hardware inforamtion.
