OCSP is a security feature that ensures that certificates issued to sites you visit have not been revoked. OCSP is disabled by default in Firefox 2, but can be enabled in Tools -> Options -> Advanced -> Encryption -> Verification.

If OCSP is enabled, you may receive errors visiting secure sites when the OCSP service chosen is malfunctioning or not available. The text of the messages can vary depending on what exactly is going wrong.

In Firefox 3, these error messages will be suppressed. There is no way to surpress them in Firefox 2 and below short of disabling OCSP.

  1. Tools -> Options -> Advanced -> Encryption -> Verification
  2. Do not use OCSP for certification validation
