It may not affect you, but when you have cascading menus you get some
of the showing/hiding events multiple times, and deleting all of the elements
more often than you should will crash firefox.

It might be helpful to look at tamperdata.mozdev.org - tamperMenu.js and
tamperPopup.js for an example of building dynamic cascading menus.
