hi, we're getting a number of similar reports in the past minutes - this is a misconfiguration on microsoft's server side. if you want to, you can disable OCSP (which is a security mechanism) in the firefox options > advanced > certificates panel until MS will fix the issue.

As another possible workaround you can temporarily toggle this pref to false on the about:config page to see if disabling OCSP Stapling works for you.

  • 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.

It is best to reset this pref via the right-click context menu to true once you are done with accessing an affected website since this is a security feature.
