Ok,
My card expired and I have to update it to donate. Firefox will not allow me to do that as they say the site is unsafe.
Get back to me.
Mozilla says
secure.freerepublic.com uses an invalid security certificate.
The certificate is not trusted because it was signed using a signature algorithm that was disabled because that algorithm is not secure.
Error code: SEC_ERROR_CERT_SIGNATURE_ALGORITHM_DISABLED
