How might I disable Fire Fox from checking web site certificates?

WHY: I get too many "Secure Connection Failed" when there is really no problem. BING.COM doesn't have a bad cert according to other browsers - but FF seems to have a problem it. I would like to disable any Fire Fox checking any web site certificate. How?

Cert error is: SEC_ERROR_OCSP_INVALID_SIGNING_CERT

Thanks o

Hi

Unfortunately Microsoft 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) and 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.
