Firefox 2.0: closing a window

Andre · Oct 26, 2006

With Firefox 1.5+, I used the following code to close a window/tab:
===
<html><head>
<script language="javascript" type="text/javascript">
function closeWindow() {
window.open('','_parent','');
window.close();
}
closeWindow();
</script></head><body></body></html>
===
Since I upgraded to Firefox 2.0, it does not work - the window/tab
stays open.

Any idea how I can "load a page" that would force a window/tab close?

The fact that it even works in FF is amazing.

That is a good thing. It means script cant close a window/tab it didn't
open.

I hope not.

I understand why this would normally not be something desirable
(loading a page just to see the browser close...), however I found it
useful for my purpose.

Here's the context:

I wrote an web-app (crunchy.sf.net; python-based with some sprinkle of
javascript) that uses Firefox as its GUI: upon starting the app, it
open a new firefox window or, if one was already open, would open a new
tab. I have a menu with a "quit button" which closes the app (python
back-end) and used to close the Firefox window/tab that was open.

P.S. That code doesn't open a window for me in IE nor FF.

Here's a confirmation that it does (did) work for some people:

(It was not the original place I found this "trick", but is one
example...)

It's a security flaw, it has no useful purpose.

Flip them back to the front page of the app.

I never said it didn't work for some people. Short of a video of it
happening (which I won't do), I can only tell you - without doubt - that
it does NOT open a new window/tab for me in IE7, FF 1.5.0.7 nor in Opera 9.

The only thing it does do is close the active tab/window.

Firefox 2.0 gives the very accurate error message:

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

Why FF1.5 didn't is up for speculation.
