UI Tabs - Trouble with FF

UI Tabs - Trouble with FF

I am new to using Jquery UI. I keep running into trouble with the
Tabs. If I apply any styles to the containing divs, firefox renders
my tabs but with a huge block as the header around the tabs. Has
anybody ran into this? Works fine in IE, and if I take the styles
away from the containing "wrapper" divs, renders fine in firefox. Any
thoughts? Thanks.
