Not working with Chrome

[baderth]

Tried it with the docker install and standalone.
the POST replies 200/"OK" but chrome wont display a notification.

After that i tried your hosted sample at "mozcurius.herokuapp.com" and the outcome was the same.
FF is working, chrome (Version 50.0.2661.87 m) is not.
