The profile here is similar to bug 1223866 and bug 1223869, and it is a some kind of mix of the two. JS side hotspots:

 - 61.1% glDrawElements()
 - 10.9% glBufferSubData()
 - 4.3% glBindBuffer()
 - 4.0% glUniformMatrix4fv()

Unlike the two other bugs, when factoring in native code as well, oddly 32.7% of total application execution time is in a single function rx::CopyNativeVertexData<int,3,3,0>(), followed by 11.1% in memmove, and 6.9% in rx::CopyNativeVertexData<float,4,4,0>().

If I load the link http://beta.unity3d.com/jonas/WebGLBenchmark/ on the latest Nightly I get the following error: "An error occured running the Unity content on this page. See your browser's JavaScript console for more info. The error was: TypeError: WEBAudio.audioContext.listener.setVelocity is not a function."
Marking this as Resolved > Incomplete since the last activity on this issue was many years ago and it might not be relevant anymore. Feel free to re-open if the issue is still reproducible on your end in the latest FF versions.
