Try setting security.ssl.enable_ocsp_staplin in about:config to false.

 

This fixed it for me.

    I just discoverd too this:

     

    Microsoft needs to reboot/repair the servers that have cached this expired certificate that is used to sign the OCSP Stapling response. You should no longer experience this issue once the server that you access has been fixed. Hopefully they will fix this quickly on affected servers.

    As a 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.
