In order to provide the best user experience, browsers may selectively enable or
disable support for WebGL, or certain sub-features, in certain situations. This special
treatment is typically used to work around stability or conformance problems. The
rules in these blacklists and whitelists are currently browser-specific, although
work is underway to share them between browsers.
For WebGL in Firefox on Windows, Windows XP or newer is required. The following minimal
driver versions are required: either NVIDIA >= 257.21, or ATI/AMD >= 10.6, or Intel
driver versions from September 2010 or newer.
For WebGL in Firefox on Mac, Mac OS 10.6 or newer is required.
On all versions of Windows, WebGL is disabled on all graphics drivers older than
January 1, 2009. Additionally, on Windows XP, WebGL is disabled on ATI/AMD drivers
older than version 10.6, on NVIDIA drivers older than version 257.21, and on Intel
drivers older than version 22.214.171.12494.
On Mac OS X, WebGL is disabled on: ATI Radeon X1900, NVIDIA GeForce 7300 GT. Additionally,
WebGL's antialiasing support is disabled on most ATI/AMD cards on Mac OS X, although
WebGL is otherwise supported on these cards. The exceptions, where all features are
supported, are: ATI Radeon HD 4670, ATI Mobility Radeon HD 4670
