Can't open https site with Firefox 39

Hi there,

With the new Firefox 39, I can't open https site of Servicedesk Plus and OpManager.
Please see http://eltonoverip.com/blog/2015/07/firefox-39-0-ssl-error-weak-ephemeral-diffie-hellman-key/

Is there a plan to upgrade the website security on the next service pack?
