Google has released Chrome frame, an open source plugin that allows Internet Explorer to use the HTML 5 technology for more advanced websites. It adds the features like HTML 5 support, better Java script support, webkit and v8 engines for rendering pages in Internet Explorer.
If you don’t want to move to Google Chrome from IE then you can add this plugin to your Internet Explorer and enjoy the features of Google Chrome on your Internet Explorer. The addition of this plugin makes the Microsoft browser fast and compatible with the sites using advanced technology.
The developers can use this plugin by invoking it using meta tag. All you have to do is add some html code in the header of your file.
<meta http-equiv="X-UA-Compatible" content="chrome=1">
