GL is no longer enabled on Windows x86 _64
Build: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:2.0b8pre) Gecko/20101014 Firefox/4.0b8pre From b8pre/20101013 build, WebGL is no more enabled.

This is mysterious to me, I'm looking at the GfxInfo.cpp code and I can't understand why it's not enabled for you. Also, looking at the commits in this revision range I don't see any big suspect. I'll try simulating your config in the blocklist...
Summary: WebGL is no more enabled → WebGL is no longer enabled
In bug 604771, there is now a patch to spoof GfxInfo (it also allows circumventing the blocklist). I have spoofed as your config, and WebGL is still enabled for me. So this is not a GfxInfo bug. I am now turning my attention to bug 604395 's suggestion that it might be caused by changeset 085538a08eb2. (A confirmation of that would be useful).
I have the same error as in bug 604395 comment 8. This bug and bug 604395 seems to be related to 64-bit OS. Can it be the same issue ?
Summary: WebGL is no longer enabled → WebGL is no longer enabled on Windows x86_64
Here on both linux 64 (firefox 64) and windows 64 (firefox 32), I can't reproduce the problem.
It works in 4.0b8pre/20101102 build. So I close this bug.

Most probably it was a dupe of bug 604395, which indeed turned out to be a general OpenGL initialization bug on all platforms, and was fixed on Monday.
