Intel driver has problem with WebGL demos (see bug 594357), but this time, it is a security issue.

Mozilla/5.0 (Windows NT 6.1; WOW64; rv:2.0b8pre) Gecko/20101014 Firefox/4.0b8pre I can not reproduce. Now, I have a blank display instead.

WebGL is no more enabled on Intel graphic cards. So the issue still exists.

(In reply to comment #4) > WebGL is no more enabled on Intel graphic cards. So the issue still exists. Sorry, what do you mean? I'm not aware of us blocking WebGL on Intel cards: we're just listing OpenGL as "discouraged" on Intel cards in GfxInfo.cpp but in WebGLContext.cpp we still go on even if OpenGL is discouraged.

-> use ANGLE

It is not fixed. See crash report: 8517bbd0-dd54-462e-a530-6168f2101214

As this demo does not exist any longer and now Intel GPUs use ANGLE, I close this bug.

Shipping the needed DirectX runtime file will be done by bug 630628. However, intel OpenGL is already blacklisted, so yes the crash can't happen anymore.
