    feedback welcome

    <html>
    <head>

    <style type="text/css">
    blockquote{ border:1px solid red;margin:15px ;padding:2px;}
    div{border:1px solid blue; margin:2px; padding:2px;}

    </style>

    <script language="javas cript" >
    if(self.Node) {
    Node.prototype. swapNode = function(n){
    var p = n.parentNode;
    var s = n.nextSibling;
    this.parentNode .replaceChild(n ,this);
    p.insertBefore( this,s);
    return this;
    }
    }

    function is_all_ws( nod )
    {
    // Use ECMA-262 Edition 3 String and RegExp features
    return !(/[^\t\n\r ]/.test(nod.data) );
    }

    function is_ignorable( nod ){
    return ( nod.nodeType == 8) || // A comment node
    ( (nod.nodeType == 3) && is_all_ws(nod) ); // a text node, all ws
    }

    function node_before( sib ){
    while ((sib = sib.previousSib ling)) {
    if (!is_ignorable( sib))
    return sib;
    }
    return null;
    }

    function node_after( sib ){
    while ((sib = sib.nextSibling )) {
    if (!is_ignorable( sib))
    return sib;
    }
    return null;
    }

    function move( obj, direction ){
    while( obj.nodeName != "BLOCKQUOTE " )
    obj = obj.parentNode;

    if( direction == 1 && obj != obj.parentNode. lastChild ){
    var cur = obj;
    while (cur){
    if (cur.nodeName == "BLOCKQUOTE "){
    obj.swapNode( cur )
    }
    cur = node_after(cur) ;
    }
    }

    if( direction == -1 && obj != obj.parentNode. firstChild ){
    var cur = obj;
    while (cur){
    if (cur.nodeName == "BLOCKQUOTE "){
    obj.swapNode( cur )
    }
    cur = node_before(cur );

      Help with what? You've presented code and implied that there is an "issue"
      with Mozilla, but failed to describe it. As far as I can tell, there's
      nothing wrong, other than some undesirable padding due to the whitespace
      between block elements. You could get rid of that either by formatting the
      HTML to include no whitespace between the DIV and BLOCKQUOTE elements.
      Alternatively, you could use the DOM to delete the corresponding text
      nodes.

      Is this a request for help, or a solution?
