Chrome Frame lets IE utilize the Chrome browser's WebKit rendering engine, as well as its high-performance V8 JavaScript engine. The extra speed and HTML 5 support are necessary, said Google earlier this week, if IE users are to run advanced Web applications such as Google Wave, a collaboration and communications tool that Google launched in May.Google pitched the plug-in as a way to instantly improve the performance of the notoriously slow IE, and as a way for Web developers to support standards IE can't handle, including HTML 5. The Chrome Frame plug-in works with IE6, IE7 and IE8 on Windows XP and Windows Vista
