 Tor Browser currently has `security.ssl.treat_unsafe_negotiation_as_broken
 = false` which means that sites with unsafe renegotiation will not display
 any warnings. Unsafe renegotiation makes MITM attacks possible, so this
 setting should be changed to `true` so vulnerable sites display a warning
 (red padlock indicating broken encryption).
