This seems like it'll cause web compat issues... Does using preventDefault on the keypress handler work?

Blocking on this speculatively, need this to be confirmed (and Boris' question answered). Jaroslav - can we get a reduced html test case?

> Does using preventDefault on the keypress handler work? No, that's the problem, event.cancelable is true but event.preventDefault() doesn't prevent the TabCandy from being opened. Try attached example.
There is another bug I found when creating this example but I've filed a new bug for it - Bug 598809
> Try attached example. The attached example is preventing default action for keydown. You said that in comment 0, and I believe you that it doesn't work. My question was about _keypress_.
Well, keypress is not even fired when CTRL + space is pressed. TabCandy seems to be activated on keydown and prevents all other key events being fired when TabCandy is active (which make sense).
Ah, so tabcandy does in fact use a keypress listener (see _setBrowserKeyHandlers in browser-tabview.js). However: 1) It uses a capturing listener in the non-system group. Why, exactly? Seems like this is what the system event group is for. 2) It doesn't pay attention to whether the default action has been prevented (which it _may_ be even at the beginning of the capturing phase of the normal event group by preventing default on keydown; some of that stuff is weird)

(In reply to comment #9) > 1) It uses a capturing listener in the non-system group. Why, exactly? Seems > like this is what the system event group is for. Capturing listener in default event group for things which chrome wants to handle before content. Sounds like TabCandy shouldn't use that, but capturing listener in system event group. (or if it is ok that .stopPropagation() prevents TabCandy, then bubble phase in default event group is also ok) > 2) It doesn't pay attention to whether the default action has been prevented > (which it _may_ be even at the beginning of the capturing phase of the > normal > event group by preventing default on keydown; some of that stuff is weird) Yeah, TabCandy listener should check event.getPreventDefault()
Bug 592183 should fix this by using a standard <key> element and getting rid of the custom event listener.
Indeed, I think this is now resolved by bug 592183, per comment 11.
