Firefox shows this error while visiting some Microsoft sites: MOZILLA_PKIX_ERROR_OCSP_RESPONSE_FOR_CERT_MISSING
I tried visiting the Microsoft and Xbox websites but both of them didn't load and Firefox showed me this error without allowing me to access the websites anyway (I'm using Firefox on Windows 10):
Secure Connection Failed
An error occurred during a connection to www.xbox.com. The OCSP response does not include a status for the certificate being verified.
Error code: MOZILLA_PKIX_ERROR_OCSP_RESPONSE_FOR_CERT_MISSING

You can update to 95.0.1 via "Help -> About Firefox" to get a fix for this issue.
If you have modified security.ssl.enable_ocsp_stapling on the about:config page then reset the pref to re-enable OCSP.

Currently only SHA1 in CertID is supported for a Stapled OCSP response in Firefox. Currently some servers have started using SHA2 in CertID and that causes the MOZILLA_PKIX_ERROR_OCSP_RESPONSE_FOR_CERT_MISSING error message. This is being worked on by Mozilla and an initial fix is ready for testing and will be ported to current releases via an update. As a workaround for now you can disable OCSP stapling in Firefox, but since this is a security feature to check the validity of a certificate then best to only disable this if you get an error visiting MS websites.

Hi
Just a quick note to ask you to look out for an update to Firefox that should be with you very soon that should resolve this issue.
If you have used a temporary workaround in about:config, I recomend that you reverse this measure at this time.
