Mozilla Firefox Security Certificate

I don't know if you are aware of this or not. But, when I attempt to log on to the Eccie site using Mozilla Firefox, I get the following message:

"www.eccie.com uses an invalid security certificate.

The certificate expired on Thursday, March 15, 2018, 6:59 PM. The current time is Thursday, March 29, 2018, 9:34 PM.

Error code: SEC_ERROR_EXPIRED_CERTIFICATE
