Comment (by cypherpunks):

 >Can site to have some information
 Just tested, outerHeight (or any else size) properties just after
 window.open() returns requested or size to which was limited by platform.
 Fingerprinting works if size limited. If not limited than that fact leaked
 too. Fingerprints around.
 dom.disable_window_move_resize can't to fix it of course.
