HTTPS issues in Firefox 39

At some point since the weekend my Firefox updated to version 39 and I can no longer visit any page of my store beginning with HTTPS. I can still browse my store at http://weatheringsolutions.mycafecommerce.com/ but not at https://weatheringsolutions.mycafecommerce.com/ and I also cannot log in to the admin panel. The secure pages work in Internet Explorer and in Firefox 37 on another computer. However, I noticed that computer seems to complain that the encryption is only partial and/or not strong enough. During a test with Firefox 28 I saw no complaints about encryption...strange! I have attached screenshots from Firefox 28, 37, and 39 showing the cafecommerce login page (or lack of). Please help.

Update: While surfing the 'net I came across this possibly relevant bit : https://developer.mozilla.org/en-US/Firefox/Releases/39/Site_Compatibility#Security

It appears newer versions of firefox are blocking sites that have an older encryption algorithm. I've alerted Dreamhost since this is a hosting issue, and hopefully it will be updated soon. Thanks for bringing this to our attention.

Update: The issue has been fixed. I was partly mistaken in my previous post; the error was specific to the use of the RC4 cipher and not the HTTPS protocol. Thanks.

Please tell Dreamhost that their certificates have now expired and all TLS connections error out. See the attached error screen from Firefox. This is becoming silly...I get the feeling DreamHost and WebAssist don't really take CafeCommerce customers seriously. Also, the Google OpenID user authenticaiton for these forums doesn't work anymore, as it was depricated in November of last year and shut down on April 20. Sigh. https://developers.google.com/identity/protocols/OpenID2Migration#shutdown-timetable

Update: I now see the certificate has been updated so the downtime was minimal. Thanks. The Google OpenID issue remains though.

Thank you for bringing the openID issue to our attention. We will update it to use openID connect as suggested in the article you linked.
