About this Add-on
You could set all of these settings yourself in about:config, but too many websites don't support secure SSL. This addon allows you to quickly toggle to default settings with alt-t-s. Secure settings will always reset when you start Firefox.
CipherFox Secure will display the current Add-on bar and Site ID dialog.
CipherFox Secure disables the following ciphers, leaving only 256 bit ciphers (in FF 25). It also requires TLS version 1.1 or 1.2, and disables insecure SSL handshakes. The cipher blacklist is subject to revision from feedback, and I don't intend to blacklist the new GCM cipher.
