This is new tool. Google Chrome Frame is an open source plug-in that brings HTML5 and other open web technologies to Internet Explorer.
Google Announced it on 22nd September via The Chromium Blog
To start using Google Chrome Frame, all developers need to do is to add a single tag:
<meta http-equiv=”X-UA-Compatible” content=”chrome=1″>
When Google Chrome Frame detects this tag it switches automatically to using Google Chrome's speedy WebKit-based rendering engine. It's that easy. For users, installing Google Chrome Frame will allow them to seamlessly enjoy modern web apps at blazing speeds, through the familiar interface of the version of IE that they are currently using.
We believe that Google Chrome Frame makes life easier for web developers as well as users. While this is still an early version intended for developers, our team invites you to try out this for your site. You can start by reading our documentation. Please share your feedback in our discussion group and file any bugs you find through the Chromium issue tracker.
