1.Standards ComplianceThe
Microsoft IE 9 team submitted tests for various Web specs that are either unratified or in transition. Their focus has been to seek compliance with HTML5, SVG 1.1, CSS 3.0, ECMAScript 5 and DOM L2 and L3 specs. Microsoft officials say that developers only have to write their code once and it will run across all browsers.
2.Hardware Accelerated Graphics IE 9 can power HTML5-coded audio and video using the device's underlying hardware. Multimedia can run natively in
IE 9 without relying on add-ons such as Flash or Silverlight.
IE 9 taps into the device's graphics processing unit (GPU) to optimize performance.
3.Google UI The new Microsoft browser adopts the "popular sites" opening screen seen in Google Chrome.
IE 9 also lets users search the Web using the address bar (or "One Box," as Microsoft terms it) of the browser, a feature seen in Google Chrome.
4.Windows UI Features introduced in
Windows 7 and
Windows Vista can be seen in
IE 9, such as the ability to pin Web sites to the taskbar as if they were applications. Developers can associate "jumplists" (a Windows term for a series of links) with pinned sites to facilitate navigation.
5.Chakra! Let's face it,
IE 8 is slow.
IE 9 uses a new JavaScript engine called "Chakra" to speed performance. Chakra is capable of taking advantage of multi-core hardware.
6.Architecture The
IE 9 team moved the processing of JavaScript closer to the Document Object Model (DOM) in the
IE 9 beta, which has resulted in speed improvements. Microsoft tests show that
IE 9 equals or surpasses competing browsers in terms of speed.
7.Performance Advice Microsoft included an "add-on performance advisor" in
IE 9 that tells users when third-party additions are slowing the browser's performance.
8.Better Security for Downloads IE 9 includes a new download manager that uses the Microsoft "smartscreen filter" to alert users when a download originates from an unfamiliar or untrusted source.
9.Tab Isolation Microsoft claims that tab isolation is a new feature in
IE 9. It provides for automatic crash recovery and hang recovery when Web sites fail.
10.Management and Dev FeaturesHitting the
F12 key lets Web developers debug their code or check performance issues. Developers can control how their Web sites appear by falling back to earlier Internet Explorer versions using
IE 9 compatibility-mode settings. IT pros can set Group Policy for
IE 9, with more than 1,500 options, including control over browser add-ons.
IE 9 will support slipstream installations, allowing IT pros to include updates in distributions.
