No, it's not built-in (like, how many people would know what to do with it?) But like I pointed out, it's easy enough to add.
The website is also most likely designed around IE and so any javascript and html code is unlikely to work in the desired way on Firefox.
One of the suggested browsers to use is "Netscape"; if it works for Netscape then probably the only thing that doesn't work right on Firefox is the braindead browser detection.
Still, it's safe to say that this is one post that went spectacularly off-course: considering that it was the person's first post, can you see any reason why posting here might have seemed like a sensible idea?
We're not going to be any help, really. What the original poster needs is for the monkeys who coded the site to put down their bananas and fix it.
