Trust Company Certificate In Firefox

By default, the Firefox doesn't trust the company's certificate, that may cause user will recieve certificate error, and unable to view the site. However, we can manually configure the Firefox to trust the company certificate to resolve the issue.

  • Open Firefox config page by run about:config and click "I accept the risk!" to continue
    • Changed the value of entry security.enterprise_roots.enabled to true
  • Export the company root certificate
    • Use portecle to export the certificate as PEM file
  • Open the Firefox option page
    • Navigate to Certificates section
    • Click the View Certificates button to open the Certificate Manager window
    • Import the PEM certificate exported in above step, click the OK button to take effect

Now, the Firefox will trust the company certificate.
