When I took a closer look on the one vivi sent it was not really answered, but you are asked about your devices and systems, browser … So for a real answer you all need to offer more information.
Edit:
Btw it is the same with this one (you know, when you get the feeling do not answer or you might open Pandora’s Box) …
