BTW, finally released today
I was testing it in different browsers and found out that Opera is a bad one.
Here is what it says: http://petromi.com/get/3aadda1b8e.png
And there so many of these nasty Opera popups that user can't close them.
It looks like Opera is not the fan of making HTTP POST request from HTTPS page (facebook page).
I've used Firefox console to find out where POST requests are coming to.
POST requests are made to http://api.playerio.com. (http://petromi.com/get/529039c12b.png)
Anything we can do here?
