Since installing Windows 10 on my desktop, EVERY site I visit on Mozilla says "This connection is untrusted," is there a fix?

I have checked your support forum, and none of those solutions work for me. I also have a new laptop & have installed Windows 10 there; no problems. The desktop with the issues is a couple of years old & a Dell, the laptop is HP. Thanks

Check the time and date of your computer with your current time and date.This should fix the error in most cases. (Or) Try this link click me.Hope it helps.

The time & date on my PC are correct. I am not able to use any webpages on mozilla. Each page says "This connectino is untrusted."

Thank you

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.

There is security software like Avast and Kaspersky and BitDefender that intercept secure connections and send their own certificate.
