I get this at every Microsoft.com site: Error code: MOZILLA_PKIX_ERROR_OCSP_RESPONSE_FOR_CERT_MISSING

Can it really be true the Microsoft needs to update their certification?

This is annoying because I am trying to use the Help function in Excel and it cannot connect. I also tried direct addressing to Microsoft.com from my browser. Same result. Thanks.

Until it gets fixed, try to enter about:config in the URL bar and set security.ssl.enable_ocsp_stapling = false.

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.

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.
