IETF rule broken with OCSP verification enabled.
I'm using firefox with OCSP verification turned on (security.OCSP.require set to true in about:config). When I try to read an RFC at ietf.org (e.g. http://www.ietf.org/rfc/rfc4086.txt ) I consistently get the error message:
Secure Connection Failed
An error occurred during a connection to www.ietf.org. The OCSP server has refused this request as unauthorized. (Error code: sec_error_ocsp_unauthorized_request)
The only "solution" is to turn off ocsp verification globally (or to disable the https everywhere IETF rule).
