How can I close a window with Javascript on Mozilla Firefox 3?

function closeWindow() {
    netscape.security.PrivilegeManager.enablePrivilege("UniversalBrowserWrite");
    alert("This will close the window");
    window.open('','_self');
    window.close();
}

closeWindow();

For security reasons, your script cannot close a window/tab that it did not open.

The solution is to present the age prompt at an earlier point in the navigation history. Then, you can choose to allow them to enter your site or not based on their input.

Instead of closing the page that presents the prompt, you can simply say, "Sorry", or perhaps redirect the user to their homepage.

This code works for both IE 7 and the latest version of Mozilla although the default setting in mozilla doesnt allow to close a window through javascript.

Here is the code:

function F11() { window.open('','_parent',''); window.open("login.aspx", "", "channelmode"); window.close(); }

To change the default setting :

1.type"about:config " in your firefox address bar and enter;

2.make sure your "dom.allow_scripts_to_close_windows" is true

self.close() does not work, are you sure you closing a window and not a script generated popup ?
