Third-party cookies problem in X-notifier for Firefox

Forums:

When X-notifier tries to login, third-party cookies should be allowed in Firefox.

If not, X-notifier cannot login.

You can change this settings in Firefox.

 Options -> Privacy & Security ->  Enhanced Tracking Protection -> Custom

 Uncheck "Cookies"

 Or  select "Cookies from unvisited websites"

However, this is less secure way. I recommend to use X-notifier Neo.
