Revoked old certificate and Firefox thinks the new certificate is revoked
I have a site where the old certificate was about to expire. I installed a new one and revoked the previous certificate. Now Firefox and only Firefox is reporting the new certificate as expired. Safari, Edge, IE, and Chrome are all seeing the new certificate as valid. Anyone have a clue as how to fix this?

Firefox still uses OCSP, unlike some other browsers.
Could you double-check using: https://www.ssllabs.com/ssltest/
If you think Firefox may have cached the old certificate and that is preventing it from seeing the new one, and that persists after a normal browser restart, you could consider removing the cert9.db file as mentioned in this article: What do the security warning codes mean?
From more research it appears Firefox still is using the CRL file. My CA seems to have screwed up and put the new certificate's serial number in the CRL file. I am installing a new certificate.
