I have a Spry menu on this page: http://www.allaboutbags.ca/notmadeincanadamyth.html
when I view it in IE it is perfect (a straight black menu bar across the page) but when I view it in Firefox all the menu items are bumped to the right of the page stacked on top of each other...I'm not a programmer so I'm not sure what to do! Any help would be greatly appreciated!
