Re: Internet Explorer 9 tops first HTML5 conformance test
IE9 as per one report, does a lot more than IE8, also supporting Canvas graphics and SVG, and some HTML5 audio and video.
But it is not so perfect, means a few sites still don't render correctly, though these are a small set of minority sites. However, the alternative is "Compatilbility Mode" button (a broken page).
On the other hand, strength of the Google Chrome browser also named the most vulnerable application considering success in test of the "Dirty Dozen" list by including a variety of vulnerability types -- cross-site scripting vulnerabilities and buffer-overflow. Some security exploits of vulnerabilities were also found involving risk for the entire organization and other desktop user applications.
