122999 - window.close() shuts down browser window with no warning

Status: VERIFIED DUPLICATE of bug 32571

(Core :: JavaScript Engine, defect)

Description

Just going to this url will close the browser window, no warning or anything.

Any other windows will continue as before. If you have multiple tabs open, it
will still shut down the entire window, not just the tab.

I had my prefs set to reopen the last url visited - which was this url, so every
time I opened Mozilla it instantly shut right back down.

So MAKE SURE to have other Mozilla windows open before going to this url. (And
then click on some other link in the other window, to reset your last url.)

Reporter: Please always specify which "Build ID" you are using,
as found in the title bar of the main Mozilla window.

I tried to set it in the version drop down, but all it had was "Other".

I did some more investigation, for various reasons my proxy server is returning
this page as a window.close() script instead of the real page.

So; this bug is actually: when opening a page with a window.close() script in
it, Mozilla shuts down the window without asking the user first. Per the spec:
the browser needs to ask permission to close the window, unless the window was
created in a script.

This is also related to bug 103452.

I will attach a small page with a window.close in it to demonstrate.
