4.3 Set Security TLS Version Minimum

Information

This feature sets the minimum protocol version that may be used when negotiating TLS/SSL sessions.
Setting TLS 1.0 as the minimum protocol version mitigates the risk of negotiating an insecure protocol, such as SSL 2.0.

Perform the following procedure:

* Open the mozilla.cfg file in the installation directory with a text editor

* Add the following lines to mozilla.cfg:

lockPref("security.tls.version.min", 1)
