@Raziel:
Yes, content blocking is set. I also spoof as IE8 (but popup also appears when spoofing as Odyssey Web Browser or Firefox). Strange enough when surfing that site with normal Firefox this popup also does not appear!
When ID is set to Odyssey I can at least close the popup on the first example below!
The popup can be seen at this screenshot:
Not working popup from this site can be seen here (clicking the little x does not do anything in Odyssey here - popup stays open):
