IE 9 features decent support for HTML 5 (the new generation of media-rich websites use this language), and now finishes the Acid 3 test with a near-perfect 95/100.
Internet Explorer 9 also offers improved speed and performance, as well as better compliance with web standards and new technologies. The new Performance Advisor add-on identifies add-ons that are slowing Internet Explorer down (a feature badly needed in Mozilla Firefox). IE 9 also lets you 'pin' websites to the Superbar and allows you to bookmark your favorite websites as 'applications' in your OS. Among the new features included in Internet Explorer 9 are better integration with the Windows operating system and a seriously beefed-up security system.
