So, how do you figure this out? Educate me. I know that (some of) you view it as a consulting opportunity, well I promise to advertise diligently for you if you help me :-)
I just opened a newspaper site because I'm flying 2 days from now and an airline strike was brewing, and I got the mixed content warning. I don't have weeks to do the investigation, or even hours. I need the information now.
How can I get at this? I have these extensions: Perspectives, Error console, DOM inspector, Web console, Live HTTP headers. None of these seem to give a simple way to trace and list connections without a huge load of extra junk that needs filtering.
