Firefox version 113.0.2 on Windows 10 Displayed: Error code: SEC_ERROR_OCSP_MALFORMED_RESPONSE

Website loads fine in Chrome and Edge. Certificate verified as valid. Website hosted on SquareSpace. This is a known issue with Firefox as there are many reports with Firefox falsely reporting this error with websites hosted on SquareSpace. Occasionally happens with major sites such as google.com.

      • Verified Firefox issue as there are many reports of this issue.

Cache and all site data cleared. No Proxy set. Endpoint protection security software disabled.

As this is a known Mozilla Firefox issue this needs to get fixed now!

Additional update Disablling OCSP Stapling in about:config -> security.ssl.enable_ocsp_stapling = false allows website to load to verify the Certificate is valid in Firefox showing it is a Firefox issue.

OCSP is a security feature and if the website supports OCSP Stapling then Firefox always checks whether the OCSP response that is stapled on the server is valid unlike other browsers that aren't that strict and are more forgiving when there is an issue. A server needs to make sure that the OCSP response is valid.
