This is about some MS servers that are sending an OCSP response via OCSP Stapling that is signed with an expired certificate. This needs to be fixed by Microsoft and affected servers need to be rebooted or updated. Microsoft is aware of this.

You can temporarily toggle this pref to false on the about:config page to disabling OCSP Stapling works for you. It is best to reset this pref via the right-click context menu to true once you are done with the affected website.

  • security.ssl.enable_ocsp_stapling = false

You can open the about:config page: via the location/address bar. You can accept the warning and click "I'll be careful" to continue.
