Enabling TLS v1.1 on Firefox 23

Change the following settings in Firefox's about:config to enable TLS v1.1.

Enabling TLS 1.1 in Firefox 23

Steps

  1. Open a new tab and type about:config into the address bar.
  2. Search for tls.version.
  3. Set security.tls.version.max to 2. This enables TLS 1.1.
  4. Set security.tls.version.min to 1. This disables SSL 3.0.

Be aware that setting tls.version.max to 3 will enable TLS v1.2 in a future release of Firefox, but setting it to 3 in version 23 actually makes it fall back to using only TLS 1.0. So for now, set it to 2.
