Hi Developers

Using Firefox, today I am unable to logon to https://www.mythtv.org.
Using Chrome I am able to logon.

Firefox message is this:

Secure Connection Failed

An error occurred during a connection to www.mythtv.org. Invalid OCSP
signing certificate in OCSP response. (Error code:
sec_error_ocsp_invalid_signing_cert)

    The page you are trying to view cannot be shown because the
