If you read my post, you would see that Firefox works fine. Maybe your install is faulty, or there are some preferences about Javascript that are checked and should not be, maybe you did not update Firefox for a while. In my system it does work. Which means, this is not a Firefox problem per se.
Hmmm...joemikeb, dkmarsh, and I do not get working links from Firefox, same as kevs. (FF 4.0.1/JavaScript enabled)
I dunno.
