Simply starting FireFox, not attempting to browse any site, results in MalwareBytes complaining of "malicious website" ocsp.digicert.com. Why is FireFox without my authorization accessing such a site?

Chosen solution

That is likely a check for the validity of a certificate via OCSP (Online Certificate Status Protocol).

Accessing such a website should be quite normal and I don't know why MalwareBytes would complain. DigiCert is a well know issuer of certificates and Firefox includes a few DigiCert root certificates.
