I receive the message below each time I use Firefox. None of the recommended fixes have worked. I've tried reinstalling Firefox but the problem reoccurs. Help! This is the message I receive:

This Connection is Untrusted

You have asked Firefox to connect securely to www.google.ca, but we can't confirm that your connection is secure.

Normally, when you try to connect securely, sites will present trusted identification to prove that you are going to the right place. However, this site's identity can't be verified. What Should I Do?

If you usually connect to this site without problems, this error could mean that someone is trying to impersonate the site, and you shouldn't continue.

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.

Chosen solution

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.

And found it's Kasperksy Internet Security that was causing me this problem, so I turned off "scan encrypted connections" in the "Network settings" section and this fixed it. thanks cor-el


EDIT: well, it started again about an hour later, so I turned off Kaspersky web anti-virus and this fixed it, again. I know I'm running an older version of Kaspersky, I don't like the newer ones. The reason I went after Kaspersky is because everything was working since I installed windows 7 about a week ago, then last night I installed Kaspersky, and today the problem started, and when I disable Kaspersky, the google problem goes away..... Oddly enough, to test this, I turned the "web anti-virus" back on, and I'm able to use google, so I'm still not sure what part of Kaspersky is doing this........ but it has to be kaspersky......

Last edit: I had to do both, now it's working fine.
