ww.youtube.com verwendet ein ungültiges Sicherheitszertifikat. Dem Zertifikat wird nicht vertraut, weil das Aussteller-Zertifikat unbekannt ist. Der Server sendet eventuell nicht die richtigen Zwischen-Zertifikate. Eventuell muss ein zusätzliches Stammzertifikat importiert werden. Fehlercode: SEC_ERROR_UNKNOWN_ISSUER
