Hi everyone...ok...I have to do a quick website for a class project....here is the link: www.cianflonestudio.com/pshopper .... all the buttons are done using CSS for the rollover effect....it works fine in IE and it looks like crap in firefox....any ideas on how to get it working in both browsers?

here is the css:
body {
background-color: #333366;
font-family: arial;
}
h2 {
width: 99.9%;
padding-left: 5px;
font-size: 145%;
font-weight: normal;
font-style: italic;
background-color: #d6d6d6;
color: black;
letter-spacing: 2px;
border-bottom: 1px solid #a5b5c6;
border-top: 1px solid #a5b5c6;
}
a {
color: maroon;
}
ul#mainNav {
list-style: none;
margin: 0;
padding: 0;
background-color: #d6d6d6;
}
ul#mainNav li a:link, ul#mainNav li a:visited {
padding: 10px;
text-decoration: none;
display: block;
width: 88%;
}
ul#mainNav li {
border-bottom: 1px solid #a5b5c6;
}
ul#mainNav li a:hover {
background-color: #43616b;
color: #eee;
}
table#main {
position: absolute;
top: 0px;
font-weight: bold;
font-size: 80%;
border: 1px solid black;
background-color: white;
margin-left: 10%;
width: 80%;
}
table#innerTable {
font-weight: bold;
font-size: 100%;
width: 100%;
}
#header {
border-bottom: 1px solid black;
background: url(topLogo.jpg);
height: 87px;
}
#links {
width: 22%;
border-left: 1px solid black;
background-color: #d6d6d6;
}
#footer {
border-top: 1px solid black;
font-weight: normal;
text-align: center;
color: #777;
font-size: 89%;
}
#formStyle {
text-align: center;
}
.mainArea {
padding: 2px;
}

and here is the html:
<html>
<head>
<title>
Personal Shopper
</title>
<link rel="stylesheet" type="text/css" href="pshoppercsss.css" />
</head>
<body>
<table cellpadding="0" cellspacing="0" id="main">

<td id="header">

<table id="innerTable" cellpadding="0" cellspacing="0">
