Error code: SSL_ERROR_NO_CYPHER_OVERLAP what in the hell do i do?????????
SSL_ERROR_NO_CYPHER_OVERLAP Your server apparently doesn't offer any cipher suites necessary to establish a secure https connection that are supported in Firefox. You can check what kind of cipher suites Firefox can make use of by visiting; https://www.ssllabs.com/ssltest/viewMyClient.html
Firefox will just show the SSL_ERROR_NO_CYPHER_OVERLAP error when encountered any site using the RC4 cipher.
Interesting. I use Firefox v54 as my default and had no problem. But when I used the current version, I got: Error code: SSL_ERROR_NO_CYPHER_OVERLAP
There is security software like Avast, Kaspersky, BitDefender and ESET that intercept secure connection certificates and send their own.
