JavaScript Copying to clipboard? Disabled?

[<ABX]

I use a few sites that add a handy tool that copys text to my clipboard

This is the script they use:

function toclip(cmd) {
  if (window.clipboardData) {
    window.clipboardData.setData('Text', cmd);
  } else if (window.netscape) {
    netscape.security.PrivilegeManager.enablePrivilege('UniversalXPConnect');   
        var str = Components.classes["@mozilla.org/supports-string;1"].createInstance(Components.interfaces.nsISupportsString);
        if (!str)
          return;
        str.data = cmd;
        var clip = Components.classes['@mozilla.org/widget/clipboard;1'].createInstance(Components.interfaces.nsIClipboard);
        if (!clip)
          return;                
        var trans = Components.classes['@mozilla.org/widget/transferable;1'].createInstance(Components.interfaces.nsITransferable);
        if (!trans)
          return;
        trans.addDataFlavor('text/unicode');
        trans.setTransferData('text/unicode',str,cmd.length*2);
        var clipid = Components.interfaces.nsIClipboard;
        clip.setData(trans,null,clipid.kGlobalClipboard);
  }
        return false;
} 

I am using Firefox 1.0 and IE 6.0 (XP SP2) and this function does not work on both. I think it may have something to do w/ sp2 because this is a pretty fresh install (1.5months)

I didnt, just notice it... it has been hapening for a while... just been too lazy to do anything about it.

Any ideas?
