Bug#752674: Upstream bug

[Pietro Battiston]

This seems quite similar to
https://bugzilla.mozilla.org/show_bug.cgi?id=1015175
... but my browser does not crash with mapy.cz .

Could you check if the following sites also crash your browser?
http://www.emojitracker.com/
http://qcplayground.withgoogle.com/
https://www.google.com/maps/views/streetview
https://developer.mozilla.org/fr/demos/detail/tower-defense/launch

(all but the first do crash mine)
