How to make firefox from blocking legit sites 2016

Được đăng

I've had no problems with this before, but today, Firefox began blocking legitimate sites such as google. ca It tells me my connection is not secure. Error code: SEC-_ERROR_UNKNOWN_USER

My security settings have not been changed, so I don't know where to even start solving this problem.

I'm not a computer wiz, so would appreciate support that I can follow...

Thanks! JK

There is security software like Avast and Kaspersky and BitDefender and ESET that intercepts secure connections and sends their own certificate or that incorporates special web shielding features that can block content.


Check out why the site is untrusted and click the "Advanced" button to expand this section to see extra details. Click the "Add Exception" button to inspect the certificate in the Certificate Viewer.

If you can't inspect the certificate via "Add Exception" then try this:

Open the "Add Security Exception" window by pasting this chrome URL in the Firefox location/address bar and check the certificate:

  • chrome://pippki/content/exceptionDialog.xul

In the location field of this window type or paste the URL of the website with the https:// protocol prefix (https://xxx.xxx).

  • retrieve the certificate via the "Get certificate" button
  • click the "View..." button to inspect the certificate in the Certificate Viewer

You can inspect details like the issuer and the certificate chain in the Details tab of the Certificate Viewer. Check who is the issuer of the certificate. If necessary then please attach a screenshot that shows the Certificate Viewer with the issuer.
