Discover the F12 developer tools in IE9

The developer tools that come with Internet Explorer 9 (F12 devtools as we call them affectionately) are a powerful aid to solving compatibility, network, script profiling and performance issues; debugging code; managing HTML and CSS; editing on the fly and validating markup; and last but not least inspecting HTML, CSS and JavaScript. Personally, the F12 devtools have already helped me a lot in understanding how some sites implement some of the new HTML5 features such as <canvas>, <video>, SVG and more.

Although the developer tools have been around in some form since Internet Explorer 7, with IE9 we get some real extra goodness. That includes things like the Network tab, which lets you see what is sent to the server, request headers, response body, response codes, inspect cookies, MIME types, Ajax and Activex calls, get information on the call initiator and much more. Other new additions are the Console tab and the User Agent string changer.
