With the help of the root certificate Kaspersky Endpoint Security for Windows deciphers and analyzes the encrypted traffic. The root certificate is added to the OS certificate storage upon the application installation. 

Mozilla Firefox and Thunderbird use their own certificate storage. To avoid errors related to the control of encrypted traffic, Kaspersky Endpoint Security for Windows reconfigures Mozilla Firefox and Thunderbird to make them use not theirs storages but the system certificate storage as well. 

If you disable this option in the application settings, add the Kaspersky root certificate to the Mozilla Firefox and Thunderbird certificate storage manually. Otherwise the applications will be unable to open HTTPS-pages.
