Um, just for everyone's edification:http://www.google.com/analytics/
As can be seen, Google Analytics is a service that Google sells to customers to help them track, aggregate, and data mine their web traffic to enable those customers to then write better targeted advertisements. It has become a pervasive presence on everything from porn sites to those dealing in baby toys.
Do you see anything at all or is the page you are attempting to load completely blank? (Kinda sounds like it...)
Not knowing any more than I do right now, I'd start by looking at what add-ons you have for sure.
One more thing: I dimly remember this happening to me back when I was attempting to run Firefox 2 and Firefox 3 on the same system at the same time. Firefox 3 does not play nice with 2 - bad stuff happens, at least in my experience.
Anyhow, look at what you're running and jot back. It sounds as though something is attempting to block Google Analytics (which can be done safely and selectively with NoScript.)
It might also be worthwhile to run a different web browser and see if it has the same problem?
Jot back and let's pursue this one.
