You can set the security.tls.version.min and security.tls.version.max prefs to 0 to disable TLS and only leave SSL 3 enabled

  • 0 means SSL 3.0, 1 means TLS 1.0, 2 means TLS 1.1, etc.

Note that the sync prefs specify whether to sync the specified pref is set to true.
So with to false the security.tls.version.max is not synced in case you use Firefox Sync.
The security.enable_tls pref is no longer used and can be reset and it will be removed on the next start.
