hello Briareos, what kind of error code / error message is shown in particular when you try to connect to the server?

Hi Philipp, The message is: "Unable to Connect Securely Firefox cannot guarantee the safety of your data on <site address> because it uses SSLv3, a broken security protocol. Advanced info: ssl_error_no_cypher_overlap"

My intention is avoid this validation in Firefox when I try to access my site. There are no other options or pop up windows in the browser in order to choose an alternative other than close the page.

Thanks & regards, Briareos

hello, ssl3.0 encrypted connections can be no longer considered secure since an attack vector against them ("POODLE") has become known. please contact the webmaster in charge of the site and urge them to update the 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. this will only work on a global level though and cannot be specified on a per-site basis....

Great !!, thanks Philipp.
