Keydown Event does not work for Control, Shift and Alt keys?

more options

If you execute the following code in the browser's console

onkeydown = function(e){console.log(e);};

it should log every keypress to the console window, however, the event doesn't seem to fire when I press Control, Alt or Shift (by themselves, keycombos like Shift + W work). Trying the same in Edge for example works for every key, including the three mentioned. Am I doing something wrong or is this a bug of firefox? I should also mention that I'm using the developer edition of firefox.

It works for me in Nightly.

You're right, it seems like it works on both, regular firefox and nightly, just not on the developer version. I guess I've to wait for an update of the developer version then and use any of the other ones in the meantime?

This is strange. May be a bug in dev-ed (so it will be solved n 4 weeks). I would also compare about:config entries beginning with dom.keyboardevent.*.

dom.keyboardevent.* config entries are equal on all 3 editions, so that doesn't seem to be the problem. I guess I'll try again in a month or so.
