How to Fix Firefox Error SSL Certificate in Firefox?

Generally, throw two types of errors in Firefox:
(1) secure connection failed
(2) This connection is Untrusted

  • Secure Connection failed error comes up when the web browser does not recognise the Certificate Authority associated with the SSL certificate. You can resolve this error by adding a new CA in browser. Please follow this necessary steps:
  1. Download a certificate from an authorized CA.
  2. Select the option named as “Trust this CA to identify websites” and press “OK”.
  3. With this step, the CA is now installed in your Firefox web browser.
  4. Now, try to access the site again and everything should be error-free.
  • This Connection is Untrusted error appears due to certain technical issues such as missing intermediate certificate or mis configuration the Firefox settings.

You can resolve it for 2 ways:

  • As a basic solution to this error, there is a need to install the ‘Intermediate Certificate’.
  • After successfully installing the root and the intermediate certificate, adjust the Firefox-settings as mentioned below:
  • Go to Advance > Certificates > Validation Setup page. Now Uncheck the checkbox of ‘Use the Online Certificate Status Protocol (OCSP) to confirm the current validity of certificates’ checkbox.

Mozilla Firefox can be a personal choice for many people because it works in a reliable, secure and at a good pace. IE and Google Chrome generally lack this balance. The server did not find the step to troubleshoot the problem.
