Now which one of these test things like WebGL / WebM technologies. This benchmark is skewed towards browsers like Firefox.
Isn't Firefox on version 15 now?
Why test Palemoon 12? It is just a build of Firefox 12 with various CPU extensions enabled.

is more reliable for benchmarks of JS. Too bad they only compare to Chrome.
IE9 JS engine has been tweaked for sunspider - these results do not show this. I would question the validity of this.
AFAIK Maxthon uses Chrome engine thus the results are very similar.
They did not test browsers on IE9/10 benchmarks. Very sad. Those IE9/10 benchmarks Microsoft put out seem like a good test for browser HTML5 gaming performance.
