I agree with Rocknation. I think that each theme currently fits the content that it frames. I would say keep each theme appropriate to the content first, then maybe adjust colors or positioning of key menus, etc., if you are interested in creating a somewhat unified look between all three.
Good luck!
Nice and sharp. FF version looked fine to me too. I like the smooth background gradiant and the modern, web 2.0 color-scheme.
Nice!
