Ron, are you by chance using a software to "speed up" your internet connection, or does that particular browser use remote servers to gather pages and then send them to you?

I used to use a software that did that, but because the pages were coming through a remote IP, many of them would be blocked based on that IP, and not mine... I wonder if for some reason using your other browser made it appear as if you had an IP address in France?
(Google analytics would screw up because of that too... Their targeted ads would be way off target.)
