Wesley said pretty much everything I was going to but here are some specific things that I found hard about your site.
The colors are very hard to read for me at least. The Dark Green and Gray do not compliment the black background as well as some of your maroons and whites. Also, the navigation bar is two rows for me (in FF3) and I'm not sure if it is supposed to be or not.
Besides that I like it. I like how you integrated the FIRST movie and all of that onto a page, maybe try putting the about first page in the navigation bar?
Finally I opened up FF:IE and I scrolled over contacts and the middle of the screen turned white for some apparent reason? Maybe check into that a little.
Anyways thanks for looking out for FF first
Most people design it in IE and than make it FF compatible and some of those sites drive me crazy!
Good luck and hope to see more from you soon.
Pavan.
