Why does Firefox not let me get to my website and display:

SSL received a weak ephemeral Diffie-Hellman key in Server Key Exchange handshake message. (Error code: ssl_error_weak_server_ephemeral_dh_key)

Fix this by entering:

1) In FireFox, enter "about:config" in the URL field and press enter.

2) Accept the "This might void your warranty!" warning :)

3) In the search field at the top, enter "security.ssl3.dhe_rsa_aes"

4) Double click each result (128 and 256) to toggle the Value to "false"
