If you are using the latest Mozilla Firefox browser, you may have problems displaying chat in pools.

Decision:

1. Click the shield icon next to the address, then move the slider to disable the Enhanced Tracking Protection is ON for this site ... as in the picture.

ATTENTION - many will think that this completely disables protection! - no, only for a specific site!
On clona.ru, only Yandex and Google analytics are used, as well as chat (as a resource from outside)






2. After everything works, it is advisable to send a message to the developers (you can empty), thereby informing them of the exclusion of this site, and so that the developers can once again double-check and update their database with such sites whose users contacted them

In addition, the new version of Firefox may cause problems with other sites, not only clona.ru ... In this case, go to "Preferences \ Privacy & Security \ Custom \ Fingerprints" and uncheck it. Next, FireFox will ask you to restart the tabs.
