Well, actually, there was a bug, that's exactly that, the
_NET_WM_USER_TIME of newly firefox window is the same as the current

That means that if Firefox is the currently focused window, the new
firefox window will receive focus.

If some other window has focus then the new forefox window is unlikely
to receive focus as the user time from that Firefox window is most
likely to be too old.
