What I think is that one can not use dialog boxes while the window is closing.. since the alert dialog box comes as MODAL dialog box and it needs a parent window and while the FF window is closing, it does not allow any dialog box to display or the dialog box gets failed to achieve the parent window OR maybe something else.The Event object keeps tracks of various events that occur on the page, such as the user moving the mouse or clicking on the link, and allows you to react to them inside your scripts.
