My Firefox browser is flipping out. Almost all sites it goes to, including Mozilla sites, I get the message that the certificates don't work, but I'm allowed to add an exception.

Going to a google site gets me blocked. I get a message about an untrusted connection, and "This site uses HTTP Strict Transport Security (HSTS) to specify that Firefox only connect to it securely. As a result, it is not possible to add an exception for this certificate." It will then not allow me to add an exception, even manually, and proceed to the site.

Firefox is flipping out. I'm having trouble using it and have to go to other browsers. In the past, Firefox was my go-to browse.

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 that intercept secure connections and send their own certificate.

If you have Avast then try to disable HTTPS scanning in Avast Web Shield.
