From the crashstat, it seems to happen on Haswell-based CPU with HD4400.

And I cannot reproduce this crash on an Ivybridge-based CPU with HD4000.

I suspect it is another driver issue.

I can't reproduce it on my Intel HD6700 Win 10 as well.

I also can't reproduce this issue on my win-10 with Intel HD graphic card. Looked into the crash report, there were totally two crashes about to this. One was 52.0.2 and the other was 55.0a1. They all got the reason EXCEPTION_ACCESS_VIOLATION_READ, meaning that point access might became invalid. Since the back trace deeply in driver, there was no obvious clue to lead to root cause.

I missed to mention that you have to disable Hardware Acceleration in the Firefox properties for triggering the crash.

Closing because no crash reported since 12 weeks.
