I tried to visit a page with a WEBGL component but it still remains inactive.
Here's a copy of my about:support page http://pastebin.com/Rm4PR8Nb

In about:config, what are the values of webgl.disabled and are there any non-default (printed in bold font) values under gfx.blacklist.* ?

Does it work if you go to about:config and set webgl.force-enabled=true ?
--> if that still doesn't work, that means something is seriously wrong with your graphics driver.

Webgldisabled is set a false and al gfx.blacklist are set with default values

I tried to set webgl.force-enabled=true and visit this URL : http://www.nihilogic.dk/labs/webgl_musical_solar_system/ but i have this error message : "No WebGL found!
You need a canvas- and WebGL-enabled browser to view this demo.
See this blog post for details on how to obtain one - or watch this YouTube video if that works better for you. "

for information i use these drivers from Nvidia site : http://www.nvidia.fr/object/win7-winvista-64bit-270.61-whql-driver-fr.html

What is the value of the preference webgl.prefer-native-gl? Does it make a difference when you change it?

Also, can you start with a clean profile using

  firefox.exe -no-remote -P

Well, there's no change when i modify webgl.prefer-native-gl from false to true.
With a clean profile "firefox.exe -no-remote -P" all is ok.
