I have an html page that contains the following Javascript to open a new window:

    <script LANGUAGE="JavaScript">
<!--
// The following Javascript is for use within a window that will open a new
// window with the Javascript window.open() function.

var lastNewWindow = null;

function displayNewWindow(pageName, width, height, url, scrollable, resizable,
toolbar, win) {

  if (typeof win == "undefined" || typeof win == "unknown") win = lastNewWindow;

  if (!isWindowClosed(win)) win.focus();

  win = window.open('', pageName, 'width=' + width + ',height=' + height + 
                      ',scrollbars=' + scrollable + ',resizable=' + resizable +
                      ',toolbar=' + toolbar);
  win.focus();
  win.location.replace(url);

  return (lastNewWindow = win);

}

// Cover all bases for platforms
function isWindowClosed(win) {
  return (typeof win == "undefined" || typeof win == "unknown" ||
          win == null || typeof win.document == "undefined" ||
          typeof win.document == "unknown" || win.document == null);
}
//-->
</SCRIPT>

    <script LANGUAGE="JavaScript">
    <!--
        displayNewWindow('TestPage', 800, 600, 'page2.html',
                         'yes', 'yes', 'no', null);
    //-->
    </SCRIPT>

(I know it seems strange to have two <SCRIPT> blocks, but it is because the page
contents are dynamically generated.)

The opened web page (page2.html) contains the following Javascript to close the
first page (i.e. the opener):

    <script LANGUAGE="JavaScript">
    <!--
        top.opener.close();
    //-->
    </SCRIPT>


However, the first page is NOT closed.  Looking at the JavaScript console, it
has the following error message:

   Scripts may not close windows that were not opened by script.

Note that this worked in Mozilla 1.2b.  Not sure about 1.3.

Reproducible: Always

Steps to Reproduce:
1. Create web page that contains Javascript window.open() call to open a second
   page in a new window.
2. In the second page, have top.opener.close() Javascript command.
3. Bring up the first page in Mozilla; it should open the second page and then
   the original page should be closed.

Actual Results:  
The second page is opened in a new window as it should be, but the
top.opener.close() does NOT work and the first window remains open.

Expected Results:  
The first window should be closed when the second window is opened.

Toby, the JavaScript console is correct, although maybe a bit brief.  If a user
opened a window, that window cannot be closed by a script.  If a script opens a
window, that window can be closed with .close()

There was a bug with this before, fixed with bug 32571.  See bug 183697 for
further discussion.
