I can't get the window to close in Firefox. I also can't the page to redirect even when using window.location and window.location.assign. http://dev-project.x10hosting.com/test/login.htm

look into your scripting.
some of the code which may be ruuning fine in IE is not supported by firefox. for eg.
Dialog.confirm($('login').innerHTML
instead try to use
Dialog.confirm($('login').innerText
You will find the code regarding the same in google. I was also facing the same problem.

The sample page you linked to does not contain the code you are asking about. There are no attempts to close the page on that page, simply a login.
