posting the crash ID is enough. Your crash is caused by your Intel graphic card driver (igd10umd32.dll ). Try to upgrade the driver and if that doesn't help, disable the hardware acceleration in (alt key)/tools/options/advanced/general

Maybe related to bug 595364? Trevor, please load about:support and copy the "Graphics" details here. Thanks.

I'm afraid that the only thing we can do about this, for now, is to report it to Intel. Does anyone have a contact for the D3D driver team at Intel?

FWIW, happens on Trunk (Gecko/20120109 Firefox/12.0a1) against Intel's (beta?) Driver 8.15.10.2559 too: bp-02092b91-554a-404a-a685-1a56d2120109 Since the Crash is totally unreproducible I presume I can save myself of filing this Issue at their Forums/Support Contacts. Offtopicly speaking, wouldn't it be more efficient persuading the GPU Vendors in providing (anonymized) Symbols Data for hooking up in Socorro like Adobe does for the Flash Plugin? :-)

So it should still be useful to report it to them.

I don't think there's much left here to do. There's been no change in this bug report for over three years and we've only seen one report of this crash recently. Please reopen if you think this is something we should address.
