JavaScript Copying to clipboard? Disabled?

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

This is the script they use:

PHP Code:

---

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?

Firefox has a plug in that copies text directly from a webpage into memory. My visually impaired friend just got it for his screen reading program. I'll have to check with him to see if it worked. He has SP2.

This is a security feature in Firefox. The script must be signed or you must set the value "signed.applets.codebase_principal_support" in about:config true.
