IE9 how to trace "Internet explorer blocked this website from displaying content with security certificate errors."

Question

I have a website that IE9 says "Internet explorer blocked this website from displaying content with security certificate errors."

I have no idea what errors it's talking about however. Firefox correctly shows the site is secure and that all content is correctly served over HTTPS. The certificate is not expired. The certificate is a standard nonwildcard certificate and the application is hosted correctly on the domain and not an invalid subdomain.

Clicking the show content button that trails the warning message will refresh the page, however upon the page loading it immediately shows the dialog again. Clicking show content, rinse and repeat infinite loop.

Why does IE make things so difficult? Can someone tell me how to find equivalent information that I can from Firefox by clicking on the certificate in the Firefox url bar that lets me see the addresses of all of the images/jss/css on the page that lets me verify they are all https in Firefox.

Since the problem is not with Internet Explorer, but the generic validation of certificates, I was able to debug this with Chrome's "Console" interface (Developer Tools via F12). The URLs which were causing the SSL error were listed with the console error "Failed to load resource", and the URL was given.

Internet Explorer's "console" interface never listed these errors. Fiddler also did not indicate there was an error with the cert in any way (I'm guessing because its job is to monitor the retrieval of the content, rather than deciding what's valid).
