anche la barra dei menu in ff è trasparente, in ie6 no, ciò vuol dire che non supporta la traparenza

e nel mio file style.css leggo un bel shadow:

codice:
div#pao_search{float:right;margin-right:18px;}
input[type=submit]{color:#eee;font-family:sans-serif;text-shadow: 0px 1px 1px #000;}
input[type=submit]{font-size:13px;padding:5px 12px;cursor:pointer;}
input[type=submit]{background:url(images/input_bg.png);font-weight:bold;}
input[type=submit]:hover{background-position:0px -50px;}
input[type=submit]:active{background-position:0px -100px;text-shadow: 0px 0px 1px #000;}
input[type="submit"]::-moz-focus-inner{border: none;}
input[type=submit]{margin-left:10px;}
input[type=submit]{border:1px solid #3f2f83;outline:none;}
input[type=submit]{-moz-border-radius: 4px;}
input[type=submit]{-webkit-border-radius: 4px;}
input[type=submit]{border-radius: 4px;}
input#submit{color:#eee;}
input#searchsubmit{color:#eee;font-size:13px;}
input#s{font-size:13px;padding:5px 5px;padding-left:30px;}
input#s{background:url(images/search.png) no-repeat 8px center #fff;}
input#s{-moz-border-radius: 4px;}
input#s{-webkit-border-radius: 4px;}
input#s{
    border:0px;
    border-radius: 4px;
    box-shadow: inset 0px 0px 2px rgba(0,0,0,0.5);
    -moz-box-shadow: inset 0px 0px 2px rgba(0,0,0,0.5);
    -webkit-box-shadow: inset 0px 0px 2px rgba(0,0,0,0.5);
}
come lo sistemo?
