AJAX https and SSL verification error

Question

I have a page that loads a div via AJAX. The AJAX POST call is made in https from a page with the protocol also https.

If I visited the page being loaded into the div directly, there are no SSL issues. If I visit the parent page before loading the div, there are no SSL issues. The error only occurs when I click a link to load the content inside the div. Suddenly, there is an error with the SSL Cert. In firefox I get the following info: "Connection partially encrypted"

What's partially encrypted? The page is fetched via https, the parent is https, both have no problems on their own...

I don't get it.

@durilai:

Figured it out. There was a loading image being used during the ajax call that used the http protocol. It didn't appear because it loaded so quickly. Found it in the javascript.
