Mozilla's Web O'(pen) Wonder and Video Driver

I have recently upgraded to Firefox 4, and I must say that I love it (:
Although, I want to try out Mozilla's Web O'(pen) Wonder, but it gives me this message :



Unfortunately, while your browser supports WebGL, your video drivers may be too old. To view any of the demos tagged with WebGL, try updating your drivers at NVIDIA, AMD, and Intel.
You can still watch screencasts of the WebGL demos or fully experience our other non-WebGL demos without updating

The problem is that my Device Manager says that my video card is the latest available.
What do I do now?
