Q987 How can I access the history array, and retrieve all the previous locations visited?

<script language="JavaScript"><!--
if (document.layers) {
    netscape.security.PrivilegeManager.enablePrivilege('UniversalBrowserRead');
    var output = '';
    for (var i=0;i<window.history.length;i++)
        output += window.history[i] + '\n';
    alert(output);
}
//--></script>
