Im getting SSL_ERROR_NO_CYPHER_OVERLAP on internal web sites like HP ILO servers, Sonicwall firewalls etc. I must manage these systems with invalid certificates. How can I override? Or is the answer to just use insecure older version of firefox. There must be a way to override like in the past. Thanks you

SSL_ERROR_NO_CYPHER_OVERLAP means that the server and the Firefox browser do not have a cipher suite in common. It will never be possible to override this via an exception. You would have to use an older (possibly an ESR) version that still supports at least one cipher suite that involved servers support. If there are error messages other than SSL_ERROR_NO_CYPHER_OVERLAP then you would still have to check if it is possible to bypass this in the current Firefox release.

You can install a portable (ESR) Firefox version to access websites that do not work with the current Firefox release. The portable version comes with its own profile folder and doesn't interfere with currently installed Firefox versions.
