Actual results: Nothing Expected results: The window should close. Like EVERY OTHER WINDOW in my OS.

This behavior is caused by small icon in standard title bar by Windows, but Firefox does not display the icon, so no.

Chrome manages to behave properly without displaying a small icon in the standard title bar. Tons of people have complained about this all over the net. Firefox has broken a very basic user interaction and it should be fixed. Please figure it out. Thanks.

Furthermore, this Firefox addon fixes the problem so obviously it's an easily attainable feat. https://addons.mozilla.org/en-US/firefox/addon/restartless-app-button-quit/ Why do I have to go hunt down an addon to make Firefox act like every other program on my OS? Just fix it please.

sorry for marking, but please first look this. suggest making a new bug for Firefox's new Australis to reach this point.
