Chat is adapted to Content Security Policy
 

Czater.pl is adapted to CSP.

Content Security Policy (CSP) is used to protect against XSS attacks, CSS injection, and malicious use of frames.

In case the page already has CSP policies enabled, you do not need to add anything. However, when it supports only versions 1 or 2, the following links should be added to the white list:
