Ok, I have done the search through the forum.....I see the security issues with AJAX in FF and I checked in the URL calls, they are staying within the domain and not going to a third party. I did not write the AJAX script and I am pretty new to AJAX, my boss's son wrote it a few years ago. It was working on an older version of FF but not with the latest download. It also does not work in the latest Opera or Chrome, but works fine with IE7. Any ideas?
