Hi, Firefox issues warning while accessing websites which are signed by Internal CAs. However, we could see the same website working fine with Microsoft Edge, Google Chrome, etc. Firefox work fine while accessing websites which are signed by Public CAs. The issue is only with websites signed with internal / Private CAs. Below is the error message: Warning: Potential Security Risk Ahead Firefox detected a potential security threat and did not continue to "XXXX.XXXXX.com". If you visit this site, attackers could try to steal information like your passwords, emails, or credit card details. What can you do about it?
