Created attachment 278433 [details] testcase When the down key (Alt+Down on Windows) is pressed while a menubutton (<button type="menu">) is focused, the button's popup opens, yet the focus also shifts to the next focusable element. This is because the keypress handler in button.xul moves focus when cursor keys are pressed. As an aside, the code in button.xul should be checking to ensure that modifiers are not pressed, but it doesn't. One possible fix is just not do any navigation for menu buttons.
