The new Firefox 4 Beta is here, and comes with WebGL activated by default. You can download this new beta here: http://firefox.com/beta.

You can see the demo online here (you need a WebGL compatible browser).

More information about this demo on David Humphrey’s blog (one of the developer of this demo) and more about WebGL in Firefox Beta8 on Vlad’s blog.
