i want to connect to my FortiGate Firewall Virtual Machine via HTTPS, but when i try to do this, Firefox tell me: "Advanced info: SSL_ERROR_NO_CYPHER_OVERLAP". on the FortiGate ufficial site i found this:

If you do not see the login page due to an SSL cipher error during the connection, and you are connecting to the trial license of FortiWeb-VM or a LENC version of FortiWeb, then your browser must be configured to accept encryption of 64-bit strength or less during the handshake. (RC2, RC4, and DES with less than 64-bit strength is supported. AES and 3DES is not supported in these versions.)

For example, in Mozilla Firefox, if you receive this error message:

ssl_error_no_cypher_overlap

you may need to enter about:config in the URL bar, then set security.ssl3.rsa.rc4_40_md5 to true.

I don't think you can add ciphers to Firefox that have "aged out" over the years as they were discovered to be insecure.

Any chance Fortigate has a firmware update??

Do any other browsers work??

In relation to other devices that browsers no longer can connect to, I've seen a suggestion to use a reverse proxy which presents a modern cipher to Firefox but works with the device using an older cipher (no idea on the details). https://www.reddit.com/r/firefox/comments/3coba7/firefox_39_completely_breaks_older_sslv3_pages/csxjtvb
