I have a problem regarding my site which renders differently on firefox. on other browsers it presents a constant appearance (IE, chrome, flock) but when i tested it on firefox, it gives this appearance: [Firefox Browser Bug](http://www.mediafire.com/?vk9vdzii7pxbitr “Firefox Browser Bug”).
It has a big extra space at the bottom part of the browser. Here is the link to my HTML and CSS Code. i used 960 GS (12 cols) in my site.
HTML = [HTML Render](http://www.mediafire.com/view/?vk9vdzii7pxbitr “HTML Render”)
CSS = [CSS Render](http://www.mediafire.com/download.php?mqhbptwbgx7ic8h “CSS Render”)
