Hello vmanion, it is already the default max in 48 :

security.tls.version.max = 3 (means at least TLS 1.2)

security.tls.version.min = 1 (means at least TLS 1.0 )

please check it in about:config

http://kb.mozillazine.org/Security.tls.version.*

if you don't have the above preference double-click on the preference and change the number

thank you
