Javascript to close IE6, IE7, IE8 and Firefox without confirmation box?

Question

Suppose, I want to have a link or a button that when user click it, will close the browser without any confirmation dialog box.

It needs to work in Internet Explorer

Answer 1

That would be a major security breach. You will never be able to do that.

You can, however, close child windows the parent has opened. Say you opened a popup with a parent window, that same parent window can have a button to close the child. Never the browser.
