In future, please post about Dynamic Drive Scripts in the Dynamic Drive Scripts Help section here where I've moved this thread, and:

That's an IE conditional comment which contains an on page stylesheet which contains the 'Holly Hack'. Since the conditional is 'lte IE 7', it means that only IE versions 5 through 7 will even look at it. If you have a valid URL DOCTYPE (as it appears that you do), IE 7, and possibly 6 probably don't need it either, and might even be harmed by it. Hacks are bad because they often mess things up. But as I say, only certain versions of IE will even look at it, so FF and others would be unaffected by it, seeing it only as an HTML comment block.
You could put it in a script using document.write, but I would want a link to the demo page of the script on dynamic drive to be sure of optimal placement.
Now, the closest thing I have handy to FF 2 is NS 7. And I see in that outdated browser that the menu bunches up on the left side with the little arrow images being on the right side. I'm not sure if there is an easy fix for that or not, or if it is even the same problem that someone with FF 2 (also outdated) would see. My advice would be to tell them to update to FF 3.
