Firefox 3.7 Nightly builds now include support for WebGL, indicating that the next major release will have full support for WebGL. Google Chrome and other browsers based on WebKit are not the only ones who are getting improved 3D-rendering capabilities as Firefox has followed suit.
Vladimir Vukicevic, the developer involved in the project said that WebGL is essentially a way to access OpenGL from within the browser using the new HTML 5 canvas tag. In combination with Javascript, which has made tremendous leaps in performance, WebGL can create a new dimension of 3D graphics on the web.
Despite progress in key areas, there are still many issues that need to be resolved before WebGL become available for everyday use. WebGL still has security and portability issues. In addition, some platforms do not have support for OpenGL and so WebGL will not work on them. Simple demos demonstrating the capabilities of WebGL will be available in the very near future.
The Firefox nightly build (Minefield) can be downloaded from the Mozilla FTP.
To enable WebGL support, type about:config in the address bar and change webgl.enabled_for_all_sites from false to true.
