Hi Sitaram,
Recently the Mozilla team made a change that stopped Minefield from working with that version of Mesa on Windows -- at the same time, it made it possible to use the version which is shipped as standard with most versions of Linux.
This will be fixed sometime soon (perhaps by making a new version of Mesa available for Windows users, or perhaps by some other method) but in the meantime you're probably best-off using this older version of Minefield: <http://ftp.mozilla.org/pub/mozilla.org/firefox/nightly/3.7a4-candidates/build1/> -- this should work with the version of Mesa you got from Vladimir's site.
Cheers,
Giles

I have "Intel GMA 4500MHD" graphics card which supports up to OpenGL 1.5. Operating system is Windows Vista 32-bit. So I cannot have hardware acceleration for WebGL.
For software rendering, I installed:
Mesa 7.8.1
Minefield 3.7a5pre
Updated the about:config values as follows:
webgl.enabled_for_all_sites true
webgl.osmesalib D:\Mesa3D\Mesa-7.8.1\lib\OSMESA32.dll
webgl.software_render true
When I tried to load page:
http://learningwebgl.com/lessons/lesson02/index.html
Got an error as follows:
Could not initialise WebGL, sorry :-(
Then I downloaded OSMESA32.dll from the following site:
http://people.mozilla.com/~vladimir/webgl/webgl-mesa-751.zip
Replaced the original DLL and tried to load WebGL page, I got same error.
Please let me know what is missing in my system. Or let me know if I need to download any particular version of software to run WebGL.
Regards,
Sitaram
