December 23, 2010 by Venkat Eswarlu

Mozilla has released Firefox 4 Beta 8 with WebGL activated by default. WebGL brings 3D graphics to Firefox 4 opening the door for developers to create vivid games and new kinds of visualizations and experiences for the web. Mozilla claims Firefox 4 supports WebGL for a large number of built-in graphics cards on Mac and Windows.

If you are experiencing any issues while trying the Demos of WebGL in Firefox, check you’ve installed the latest DirectX drivers from Microsoft and ensure your graphic card supports OpenGL 2.0 drivers.

List of WebGL Supported browsers with version numbers:

  • Firefox 4.0+
  • Google Chrome 9.0+
  • Opera 12+
  • Safari 5.1+
  • Internet Explorer 11+

Note: You must note users’ devices must have supported hardware for these WebGL features.

Mozilla has enabled WebGL 2.0 support in Firefox from version 51.
