I want to run this site: But, it says that WebGL is required.

How do I install it? I have Firefox version 3.6.13 and Chromium version 8.0.552.215.

Actually it says there you need a Browser that supports WebGL, not openGl. As you can see in the following links, no officially released version of Firefox, Chrome or Opera support WebGL at 100%. The nightly builds do but they still need work:

As WebGL uses Canvas then it needs a browser that supports HTML 5 (Which is like the latest for browsers)

Also there is a web page to test if your browser supports WebGL:

Remember that apart from the Browser supporting WebGL, you need a video card that supports OpenGL ES 2.0 which would be supported if your graphics card supports OpenGL 2.0+.

With Firefox 4.x and starting with Chrome 9 you have support for WebGL apps. For course, for the time being, Chrome renders faster than Firefox but Firefox is more standard than Chrome.

Nowadays, WebGL should work in Chrome. However on some systems (mine is an NVidia Optimus) I had to go to about:flags and enable Override software rendering list, then restart Chrome.

You may also need to disable the GPU blacklist. This can be done by editing /usr/share/applications/google-chrome.desktop (with elevated permissions.)

On line 108, there's a line that reads:

/opt/google/chrome/google-chrome %U

Modify it to look like this:

/opt/google/chrome/google-chrome --ignore-gpu-blacklist %U

You can try this from the console first if you prefer.
