-Re-enable the DHE (Ephemeral Diffie-Hellman) cipher suites, which IceCat
-38.6.0 disabled by default to avoid the Logjam attack.  This issue was
-fixed in NSS version 3.19.1 by limiting the lower strength of supported
-DHE keys to use 1023 bit primes, so we can enable these cipher suites
-safely.  The DHE cipher suites are needed to allow IceCat to connect to
