Help with browser differences

I am writing an electronic card system for my company.  Everything is going great but now I have one problem between IE and Firefox.  When you view the card that was sent to you there is a Close Window button at the bottom.  This button works in IE but not in Firefox.  I can't figure out why.  Here is the code from each browser.  Any help is greatly appreciated.

Didn't work.  Here is a link that you can use to see how it works in IE but not in Firefox.

dyarosh,
From http://developer.mozilla.org/en/docs/DOM:window.open#FAQ

New windows not opened by javascript can not as a rule be closed by JavaScript.

And from
http://developer.mozilla.org/en/docs/window.close
This method is only allowed to be called for windows that were opened by a script using the window.open method. If the window was not opened by a script, the following error appears in the JavaScript Console: Scripts may not close windows that were not opened by script.
