Navigation bar alignment

Hey all – I’m sure this is a really stupid question but I’ve got to ask it as it’s driving me mad…

I’m trying to make my navigation tabs all fit within my container div and, in Safari, this works fine. However, in FF, no matter what I do, I can’t seem to get the thing to stay put… any ideas?!

Safari: [URL=”http://www.roundthebend.org/temp/images/safari.png”]http://www.roundthebend.org/temp/images/safari.png[/URL]

[CODE]* {margin: 0; padding: 0; border: 0;}
