We do know that the Internet Explorer 9 Release Candidate is now available, but does that mean it will help Microsoft claw back its market share that has eroded steadily for some time already? Still, despite the advances and new technological implementations in IE9, its rivals cannot but help themselves from sniping it from afar. Mozilla has stated that this latest incarnation of IE is not a “modern browser”, where Mozilla technical evangelist Paul Rouget has something to say about the graphic that you see above, showing references standards-happy tests from across the web, including caniuse.com and html5tests.com. This is what he shared :-

Does IE9 support 99% of the HTML5 specification as insinuated by Microsoft? No, they’re actually pretty far from it. The tests Microsoft are referring to are the ones they created during the development of IE9. It’s not that surprising that they pass the very tests they used to design and develop the browser.

Apart from that, he shares the list of standards that IE9 doesn’t support, where among them include Web Workers, offline Application Cache, HTML5 forms, JavaScript Strict Mode, the File API, and WebGL.
