User-Agent: Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US; rv:1.9.2a1pre) Gecko/20090702 Firefox/3.0 Build Identifier: According to Bug #500883, Canvas3D has been checked into trunk, but it is not yet available in official trunk builds (see "Steps to Reproduce" for a quick way to check). Apparently, it has to be enabled first via MOZ_ENABLE_CANVAS3D at build time. I can see the reasoning why this isn't yet enabled by default, but maybe we could move it to an about:config pref instead. While that would still increase binary size, that shouldn't really be a problem on trunk right now. Reproducible: Always Steps to Reproduce: 1. Open the supplied javascript url or copy try{alert(CanvasRenderingContextGLWeb20);}catch(e){alert(e);} to the error console. Actual Results: "ReferenceError: CanvasRenderingContextGLWeb20 is not defined" Expected Results: "[object CanvasRenderingContextGLWeb20]"

Whoops, this was done in 516213. Pref is "webgl.enabled_for_all_sites" for now.
