hello

During a secure connection, a website must provide a certificate issued by a trusted certificate authority to ensure that the user is connected to the intended target and the connection is encrypted. If you click the Advanced button on a "Warning: Potential Security Risk Ahead" error page and you see the error code SEC_ERROR_UNKNOWN_ISSUER or MOZILLA_PKIX_ERROR_MITM_DETECTED, it means that the provided certificate was issued by a certificate authority that is not known by Firefox and therefore cannot be trusted by default.

The error occurs on multiple secure sites In case you get this problem on multiple unrelated HTTPS-sites, it indicates that something on your system or network is intercepting your connection and injecting certificates in a way that is not trusted by Firefox. The most common causes are security software scanning encrypted connections or malware listening in, replacing legitimate website certificates with their own. In particular, the error code MOZILLA_PKIX_ERROR_MITM_DETECTED indicates that Firefox is able to detect that the connection is intercepted.

Antivirus products

Third-party antivirus software can interfere with Firefox's secure connections.

We recommend uninstalling your third-party software and using the security software offered for Windows by Microsoft:

  • Windows 8 and Windows 10 - Windows Defender (built-in)

If you do not want to uninstall your third-party software, you could try reinstalling it, which might trigger the software into placing its certificates into the Firefox trust store again.

Here are some alternative solutions you can try:

Avast/AVG:

In Avast or AVG security products you can disable the interception of secure connections:

  1. Open the dashboard of your Avast or AVG application.
  2. Go to Menu and click on Settings > Protection > Core Shields.
  3. Scroll down to the Configure shield settings section and click on Web Shield.
  4. Uncheck the box next to Enable HTTPS Scanning and confirm this by clicking OK.

note:In older versions of the product you'll find the corresponding option when you go to

Menu > Settings > Components and click Customize next to Web Shield

Bitdefender

In Bitdefender security products you can disable the interception of secure connections:

  • Open the dashboard of your Bitdefender application.
  • Go to Protection and in the Online Threat Prevention section click on Settings.
  • Toggle off the Encrypted Web Scan setting.

In older versions of the product you can find the corresponding option labelled

Scan SSL when you go to Modules > Web Protection.

The anzacavenuewreckers.com.au server doesn't send required intermediate certificate(s) that Firefox needs to build a certificate chain that ends in a trusted root certificate.

See the report:

This server's certificate chain is incomplete. Grade capped to B.
Firefox will cache intermediate certificates send by a server in the Certificate Manager for future use.
If you have visited a website that has send this intermediate certificate in the past then Firefox will not display the error page when you visit a server that doesn't send this intermediate certificate.

The server also sends an expired USERTrust RSA Certification Authority intermediate certificate.

  • Valid until Sat, 30 May 2020 10:48:38 UTC (expired 1 month and 9 days ago) EXPIRED

You can contact this website via email and ask them to look into these issues.


You can check details about the certificate chain.

  • click the "Advanced" button on the error page to show more detail
  • click the blue "View Certificate" text to inspect the certificate in the Certificate Viewer

Scroll down to the "Authority Info (AIA)" section and under Location double-click the xxx.crt link to download the missing intermediate certificate (Network Solutions DV Server CA 2).

You can install this certificate in the Certificate Manager under Authorities.

  • do NOT set any trust bits when prompted, but click the OK button
  • Options/Preferences -> Privacy & Security
    Certificates: View Certificates

If you reload the page then you should no longer get this untrusted error.
