Hello REEVREDNAV, SSLv3 encrypted connections can be no longer considered secure since an attack vector against them ("POODLE") has become known. Contact the webmaster in charge of the site and urge them to update their encryption to something contemporary. https://blog.mozilla.org/security/2014/10/14/the-poodle-attack-and-the-end-of-ssl-3-0/ If you want to re-enable ssl 3.0 in firefox you can do that - however keep the consequences in mind, that you will become vulnerable to the attack mentioned above: enter about:config into the firefox address bar (confirm the info message in case it shows up) & search for the preference named security.tls.version.min. double-click it, change its value to 0 and restart the browser.
