I have firefox 18.0.1 on windows OS. And there is a problem with TSL 1.2. In about:config this is all what I have regarding TLS:

security.enable_tls;true security.enable_tls_session_tickets;true services.sync.prefs.sync.security.enable_tls;true

There is no security.tls.version.max.

In Options-->Advanced-->Encryption there is only "Use TLS 1.0"

hi matko7, firefox 18 is unsuppported and contains dozens of highly critical security vulnerabilities that are exploited on the web. tls 1.2 wasn't present in firefox 18 either, so please update firefox to the latest version!

TLS 1.2 support was added as of Gecko 24.0 or Firefox 24.0 as the old Firefox 18.0.1 did not support TLS 1.2.
