Problemas con ie y mozilla

[javicho73]

Hola amigos; tengo un problema con un diseño que vengo haciendo, el tema es que se ve distorsionado con Mozilla mientras que en IE8 se ve bien, la idea seria que no falle el diseño en ningun navegador, por favor si me pudieran ayudar, los codigos html y css son los siguientes

Por favor, espero me puedan ayudar a ver donde esta la falla en las hojas de estilo

este es el codigo de testbasic.css

html, body {
margin:0;
padding:0;
}
body{
text-align: center;
font-family: "Lucida Grande", "Lucida Sans Unicode", Verdana, Helvetica, Arial, sans-serif;
background-color: #eee;
color: #444;
font-size: 75%;
}
a{
color: #FAD17F;
text-decoration: none;
}
a:focus, a:hover, a:active {
text-decoration: underline;
}
p, li {
line-height: 1.8em;
}
h1, h2 {
font-family: "Trebuchet MS", Verdana, sans-serif;
margin: 0 0 10px 0;
letter-spacing:-1px;
}
h1 {
padding: 0;
font-size: 2em;
color: #333;
}
h2 {
padding-top: 10px;
font-size:1.5em;
}
pre {
font-size: 0.6em;
line-height: 1.2em;
overflow-x: auto;
}
div#page {
width: 100%;
background-color: #000;
margin: 0 auto;
text-align: left;
/*border-color: #ddd;
border-style: none solid solid;
border-width: medium 1px 1px;*/
}
div#container {
padding: 20px;
}
div#ads {
clear: both;
padding: 12px 0 12px 66px;
}
div#footer {
