<canvas> elements. Support for WebGL is present in Firefox 4+, Google Chrome 9+, Opera 12+, Safari 5.1+ and Internet Explorer 11+; however, the user's device must also have hardware that supports these features.

In addition to the browser, the GPU itself also needs to support the feature. So, for example, S3 Texture Compression (S3TC) is only available on Tegra-based tablets. Most browsers make the WebGL context available through the
webgl context name, but older ones need
experimental-webgl as well. In addition, the upcoming WebGL 2 is fully backwards-compatible and will have the context name
experimental-webgl2 in the future for testing.
WebGL debugging and testing
Starting with Gecko 10.0 (Firefox 10.0 / Thunderbird 10.0 / SeaMonkey 2.7), there are two preferences available which let you control the capabilities of WebGL for testing purposes:
- A Boolean property that, when
true, enables a minimum capability mode. When in this mode, WebGL is configured to only support the bare minimum feature set and capabilities required by the WebGL specification. This lets you ensure that your WebGL code will work on any device or browser, regardless of their capabilities. This is
- A Boolean property that, when
true, disables all WebGL extensions. This is
