Comment:
The extensions are disabled. They are instantiated in
`WebGLContext::GetExtension()` only after checking whether they are
supported. This happens in `WebGLContext::IsExtensionSupported()` which is
first checking whether extensions are enabled in general and returning
early if not
{{{
if (mDisableExtensions) return false;
}}}
`mDisableExtensions` gets set in `WebGLContext::InitAndValidateGL()`
(`mDisableExtensions = gfxPrefs::WebGLDisableExtensions();`) which itself
gets called early on in WebGLContext::CreateAndInitGL)`.
