When I try to have access to www.hotmail.com Firefox reports: "Fehler: Gesicherte Verbindung fehlgeschlagen. Ein Fehler ist während einer Verbindung mit outlook.live.com aufgetreten. Ungültiges OCSP-Unterzeichnungszertifikat in OCSP-Antwort. Fehlercode: SEC_ERROR_OCSP_INVALID_SIGNING_CERT.. Die Website kann nicht angezeigt werden, da die Authentizität der erhaltenen Daten nicht verifiziert werden konnte. Kontaktieren Sie bitte den Inhaber der Website, um ihn über dieses Problem zu informieren." The same happens to two friends working with different computers. I checked the URL on SSL Labs. It gets an overall rating "B", with "Certificates 100%". Just before writing this message I got access to the front page ("Login") of hotmail. The login itself didn't work, and again, I received the message cited above. Can anyone help me?

hi, unfortunately MS has misconfigured a security feature (OCSP stapling) on their servers which got now cached in your local firefox installation.

in order to resolve that, please enter about:config into the firefox address bar (confirm the info message in case it shows up) & search for the preference named security.ssl.enable_ocsp_stapling. double-click it and change its value to false - this will degrade a security feature in firefox, so please revisit it in a couple of days again after microsoft has fixed their stuff and turn it back on again then...
