Seen while running Mozilla/5.0 (Windows; Windows NT 6.1; WOW64; rv:2.0b3) Gecko/20100805 Firefox/4.0b3. I tried in 32 bit mode and the same thing happens. STR: 1. Enable WebGL with the about:config pref 2. Load the site in the URL, or one of the demos from http://www.ambiera.com/copperlicht/demos.html Expected: it would work as it does using Windows XP and Vista using the same build Actual: I get an error saying that "This demo requires a WebGL-enabled browser" I have seen Bug 560975 and I do not have those prefs set in about:config since I am using a new profile.

I tested this on my HP TouchSmart tx2 laptop which runs Windows 7 and that machine loads the sites such as https://cvs.khronos.org/svn/repos/registry/trunk/public/webgl/sdk/demos/google/particles/index.html fine. Perhaps this is hardware related?

What is the graphics card in the machine that can't run WebGL demos?

Since 20100917 build, I have the same issue with a new profile. I checked that webgl.enabled_for_all_site is set to true. It seems to be linked to bug 594874 fix. Every Intel card as been declared as "Webgl not recommended", so webgl is not enabled. Either, "webgl not recommended" status must not disabled webgl, or at least some recent graphic cards must have "webgl available" status. Adapter Description : Mobile Intel(R) 4 Series Express Chipset Family Vendor ID : 8086 Device ID : 2a42 Adapter RAM : Unknown Adapter Drivers : igdumd64 igd10umd64 igdumdx32 igd10umd32 Driver Version : 8.15.10.2202 Driver Date : 8-25-2010 Direct2D Enabled : true DirectWrite Enabled : true GPU Accelerated Windows1/1 Direct3D 9

OK, indeed our feature tests were too strict in that "not recommended" ended up blocking. This patch relaxes them so we only block when the feature is really blocked or not available.

Marcia: still need to know what's your graphics card! If it's Intel and doesn't have GL drivers on Windows, then your issue is a dupe of the fact that we need to use ANGLE in your case (known issue).

ok, let's play safe and only do this for WebGl.

Regenerated the patch (line ending issue)
