Travel Technology - FF 2.0 and T-Mobile Hot Spot

When I open Firefox (v2.0), I can't get the T-Mobile Hot Spot page to pop up.

When I open IE, it does it fine, thus it's not Norton that's blocking it. I usually sign-in on IE, leave that open, and surf on FF.

Any suggestions from the smart people on how to get FF to open the T-Mobile page on start-up?

Could the T-mo sign-on page be an IE-only app?

I have encountered this as well; it is random, however. What I did was bookmark the URL in IE and then cut and paste the bookmarked URL into FF and voila! If it doesnt open on its own, I simply open the bookmark and it works every time!
