converting ie style sheet to work in firefox

[Mook25]

Hi,

My style sheet looks like below. It works fine in IE but the 3 columns left,mid and right are too far up the page. can anyone help with this? if possible i'd like my site to work with both and not have to make 2 duplicate sites with one working in IE and one in firefox.

body {
 margin: 0px;
                background-color: #000013;
 background-attachment: fixed;
 background-image: url(../styleImages/backgrounds/pageBg.jpg);
 background-repeat: repeat-x;
 
}
#pageSurround {
 width: 850px;
 margin: 10px auto;
 padding:0px;
 border: 5px solid #000000;
 background-color: #FFFFFF;
}
#subSurround {
                border: 1px solid #5C84CE;
 background-image: url(../styleImages/backgrounds/contentBg.jpg);
 background-repeat: repeat-x;

}
#topHeader {
 text-align: right;
