I have Windows 10. 64 bit system. HP laptop. Only version that I have found is the new one without seeing other untrusting websites that off the older versions of FF. All I'm wanting to know is if there is a trusted site that offers older versions of FF. I think the one I'm looking for is FF 29 or 29.1 Please let me know what the web address is and or how to find the older versions. Thanks

Did you investigate the cause of these issues?

You can click the "Advanced" button to expand this section and show extra details. If the certificate is not trusted because no issuer chain was provided (SEC_ERROR_UNKNOWN_ISSUER) then click the blue error message to expand this section and show the certificate chain. Please click "Copy text to clipboard" and paste this base64 encoded certificate chain text in a reply. That will allow us to check details like the issuer of the certificate.

Can you attach a screenshot?


Firefox 29 and other Firefox versions that aren't supported are not safe to use because they have known and unpatched security risks.

Only Firefox 52 ESR is still supported.
