Firefox keypress Event with Ctrl

I'm developing a firefox addon. When trying to capture the keypress event I can see the output for it on my browser console. But not if I press CTRL + TAB for example:

window.addEventListener('load', function ()  {
    document.addEventListener('keypress', function (e) {
        console.error(e);
    }, true);
}, false);

Output when pressing tab only:

keypress { target: <body.ask-page.new-topbar>, key: "Tab", charCode: 0, keyCode: 9 }

Why keypress doesn't triggers on any Ctrl combination?

As per my comment im not sure why e.ctlrKey isn't true on keypress.

What you can try getModifierState

window.addEventListener('load', function ()  {
    document.addEventListener('keypress', function (e) {
        console.error(e);
        console.error('Control down:', e.getModifierState('Control'));
    }, true);
}, false);

MDN :: getModifierState

edit:

http://jsfiddle.net/ace4tuwo/

shows you can do this in keypress with getmodifier. works as long as you use ctrl as a modifier, meaning you press and hold ctrl first
