Problems with mozilla...desperate!

Hello,

Ive got a problem with my site. Its not showing right when using Mozilla firefox. The site is supposed to cover the hole window like it does in IE, but instead it`s just a little square on the top of the window

I tried using the code below but it didn`t do the trick. Is there anybody that may help me?
I would really appreciate it. The link to the site is www.mauritzo.com

Best regards,

code:
[LEFT][COLOR=darkred]<style type=“text/css”>
<!–
body {
height: 100%;
width: 100%;
margin-top: 0px;
margin-right: 0px;
margin-bottom: 0px;
margin-left: 0px;
padding-top: 0px;
padding-right: 0px;
padding-bottom: 0px;
padding-left: 0px;
border-top-width: 0px;
border-right-width: 0px;
border-bottom-width: 0px;
border-left-width: 0px;
}
–>
</style>[/COLOR][/LEFT]
