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.
