If you're running Firefox 23 or newer, you can now choose to support newer and safer TLS encryption versions. Unfortunately, there are some very broken websites that choke if your browser declares support for these newer versions, so Mozilla has not enabled it by default.

- 0 = SSL 3.0. This should be your minimum.
- 1 = TLS 1.0. Firefox <= 22 supports this.
- 2 = TLS 1.1. Firefox 23 supports this.
- 3 = TLS 1.2. Firefox 24 will support this.
