css spacing or margin???

[karen]

I have managed to get a nav bar into my code courtesy of listomatic. My problem (image link below) is that it looks fine in IE but in Firefox there is unwanted space above and below the actual navbar.

Sorry cannot post a link as developing the site locally on xampp but here are the 2 screenshots. Problem is Firefox only.

Thanks very much for any help or pointers.
