How do I debug websites in IE10 on Win8 under Metro?

Question

I have a website that runs fine on IE10 Consumer Preview, Chrome, and Firefox all on Windows 8 Consumer Preview (i.e. Win8 beta). But in the Metro version of IE10 Consumer Preview I just see an error message: "Internet Explorer cannot display the webpage". How do I diagnose the error? F12 does not bring up any developer tools.

Answer 1

the infamous fiddler http debugger works with windows 8, allowing you to see what requests and responses are being sent to and from the server, so the browser can not hide anything from you, which is what I suspect is happening at the moment.

Answer 2

It's highly recommended to use firebug lite in IE because the native debugger is poor
