OCSP (Online Certificate Status Protocol) is a security feature that ensures that certificates issued to sites you visit have not been revoked.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 Advanced options (Encryption / Certificates -> 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 suppress them in Firefox 2 and below, short of disabling OCSP. To disable OCSP in Firefox 2:
- Go to "Tools -> Options -> Advanced -> Encryption / Certificates -> Verification".
- Select Do not use OCSP for certification validation.
