Google Chrome Frame
Start using open web technologies like the HTML5 canvas tag right away, even technologies that aren’t yet supported in Internet Explorer 6, 7, or 8. Take advantage of JavaScript performance improvements to make your apps faster and more responsive.
Making your pages work with Google Chrome Frame is easy. Just add this tag to the top of the page:
<meta http-equiv="X-UA-Compatible" content="chrome=1">
