Hello guys, I'm using this code for scroll bar style, however, it only works in IE, but now in Firefox. can anybody help me?

Code:
<!--
div.pagescroll {
 color: #333333;
 background-color:transparent;
 width:582px;
 height:360px;
 scrollbar-arrow-color:#AE8A8A;
 scrollbar-face-color:white;
 scrollbar-shadow-color:#834B4B;
 scrollbar-highlight-color:#AE8A8A;
 overflow: auto;
 overflow-x: hidden;
 padding-right:5px
}
-->
</style>
thank you!
