WebGL is currently under development, and is supported in the latest builds of several browsers. Here are instructions on how to obtain a copy of a browser supporting the provisional WebGL specification. As the specification nears completion, expect that browsers will have this functionality built in to their latest releases, and not require any manual steps to enable it.

Firefox

WebGL is supported in the nightly builds of Firefox. Visit http://ftp.mozilla.org/pub/mozilla.org/firefox/nightly/latest-trunk/ for builds on Linux (32- and 64-bit), Mac OS X and Windows.

After downloading the browser, enable WebGL: type about:config into the address bar, search for "webgl", and double-click "webgl.enabled_for_all_sites" to set it to true.

The implementation requires working OpenGL 2.1 drivers. If OpenGL is not available, software rendering can be used through Mesa, by setting the "webgl.osmesalib" variable to point to a version of OSMesa compiled with MGL namespace mangling.

Safari

WebGL is supported on Mac OS X 10.6 in the WebKit nightly builds available at http://nightly.webkit.org/ .

After downloading and installing the browser, open the Terminal and type the following: 

defaults write com.apple.Safari WebKitWebGLEnabled -bool YES

This command only needs to be run once. All future invocations of the browser will run with WebGL enabled.

Chrome

WebGL is now in the Chrome Dev channel, you can install/switch to the dev channel using the utility provided at http://dev.chromium.org/getting-involved/dev-channel

Chromium

WebGL is supported in the Chromium continuous builds for Linux, Mac OS X, and Windows. The most recent builds are available here:

Linux/32, Mac and Windows point to the folder containing chrome-linux.zip, chrome-mac.zip, or chrome-win32.zip. For Linux/64, choose the highest numbered folder. Unpack the zip archive.

Chromium must be launched from the command line in order to enable WebGL.

  • Linux: ./chrome --no-sandbox --enable-webgl
  • Mac OS X: Chromium.app/Contents/MacOS/Chromium --no-sandbox --enable-webgl
  • Windows: chrome.exe --no-sandbox --enable-webgl

Note that enabling WebGL currently requires disabling Chromium's security sandbox, which is strongly discouraged for arbitrary web browsing. Work is ongoing to remove this requirement.
