>Hmm, that FireFox (3.0.7) warning message is quite specific. I've never seen it on any other site. Have you traced the operation to make sure what is happening is what you think is happening? Can you test with FireFox - maybe it's something specific to that browser.

This page has always been fully secured. But, Firefox didn't like it that some links in it where not being reference under https. I have adjusted those that were causing this. This message should no longer appear.
