1. Download a nightly build of Firefox 4 there, and untar it:

2. Run it with the MOZ_GLX_IGNORE_BLACKLIST env variable, e.g.:
$ MOZ_GLX_IGNORE_BLACKLIST=1 ./firefox -P -no-remote
(-P allows you to create a fresh new profile and -no-remote
prevents attaching to existing firefox instance).
3. Go to this URL:
https://cvs.khronos.org/svn/repos/registry/trunk/public/webgl/sdk/tests/webgl-conformance-tests.html
I followed this to the letter, but FF4 did not detect WebGL on my
laptop.
There are two possible reasons for this.
* first, can you please go to about:config and check that
webgl.enabled_for_all_sites is true.
* otherwise, that means that WebGL contexts fail to initialize. We
require OpenGL 2.1, and once we get a OpenGL context, we perform a few
basic tests for e.g. the number of texture image units.
Do you see any error message in the terminal, or in Firefox's error
consosle (Ctrl+Shift+J) ?
I guess Gentoo needs to add OSMesa to their list of packages to
test.
If you want to use OSMesa for WebGL rendering, you need to let Firefox
know about the library filename by going to about:config and setting
webgl.osmesalib (for example libOSMesa.so.6)
