I use Firefox 63.0 (64 bits). Since 23 oct 2018 I got message "SEC_ERROR_OCSP_UNKNOWN_CERT" when connecting to my bank site LCL. I don't have this issue with Microsoft edge navigator. If I deselect OCS option in Firfox parameter the issue disappear but come back when I select again the OCS option. How this issue can be solve definitively with keeping OCS option ? Is the connection as well secure without this option ?

Issue is solved by setting to true network.dns.disableIPv6 by using about:config in the navigator address bar
