I have tried to follow all the support pages presented on this topic, but to no avail. I have uninstalled Firefox and downloaded a fresh copy, but that did not help either. Maybe there must be some file left behind which is affecting the new copy, but I can not find it.

I have never had this problem before. It is effecting sites like Google, etc.

So basically all https sites are untrusted connections

I need a fix or I will be forced to stop using my favourite browser.

What Anti-Virus security software do you have?

There is security software like Avast and Kaspersky that intercept secure connections and send their own certificate. If you have such software then check its settings.

Hi, I keep getting this untrusted connection message. I have tried posted solutions for the "this connection is untrusted" problem Firefox seems to be having. It occurs on any website I try to go into. I have tried changing date and time, running Norton antivirus scans (I have Norton 360 premier installed), change information using about:config setting, uninstalled and reinstalled Firefox and deleted "cert8.db" file, but nothing seems to work.

I tried adding images but can't attach them for some unknown reason. I am using internet explorer to send this message since Firefox not working. The error code I keep getting on every website, even on Firefox support websites are (Error code: sec_error_unknown_issuer) (Error code: sec_error_cert_signature_algorithm_disabled)

What do I do next?

Start Firefox in Safe Mode {web Link} by holding down the <Shift>
(Mac=Options)
key, and then starting Firefox. Is the problem still there?


Start your Computer in safe mode with networking. Then start Firefox. Try Safe web sites. Is the problem still there?

If you can't inspect the certificate via "I Understand the Risks" 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.

  • 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 you can attach a screenshot that shows the certificate viewer.
