View source for Cannot connect securely because the site uses an older insecure version of the SSL protocol

{{right-pic|Ssl2 disabled.png}}

This article deals with the message "''Firefox cannot connect securely to (site name) because the site uses an older, insecure version of the SSL protocol''" when trying to go to certain sites. This message is shown because starting in Firefox 2, support for SSL 2, an older and insecure security protocol, was disabled by default.

Mozilla recommends that sites do not use SSL 2. You should contact the webmaster of the site and tell them your problem. If you must access an SSL 2 site, you can re-enable SSL 2 in Firefox, though this isn't recommended.
{{EditPrefBool|security.enable_ssl2|true}}

You may also need to enable specific ciphers. Still in about:config, enter <tt>ssl2</tt> into the filter box and enable the ciphers presented.[http://forums.mozillazine.org/viewtopic.php?t=478336]
