I had an issue where my computer completely froze up and I had to force restart. When I logged back on, Firefox no longer trusted Google or Facebook. Youtube seems ok, it's just sites with "google.com" in the URL... and Facebook.

Here's the error message I am getting:

This Connection is Untrusted



You have asked Firefox to connect
securely to maps.google.com, 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.





maps.google.com uses an invalid security certificate.

The certificate is not trusted because no issuer chain was provided.

(Error code: sec_error_unknown_issuer)

I accepted that I would take the risks, but these sites won't load images. What good is Facebook without faces? Any ideas?

(A user on another site suggested uninstalling Firefox, cleaning the registry, and then re-installing. Doing this made Tumblr stop working)

Hi,

The Reset Firefox feature can fix many issues by restoring Firefox to its factory default state while saving your essential information. Note: This will cause you to lose any Extensions, Open websites, and some Preferences.

To Reset Firefox do the following:

  1. Go to Firefox > Help > Troubleshooting Information.
  2. Click the "Reset Firefox" button.
  3. Firefox will close and reset. After Firefox is done, it will show a window with the information that is imported. Click Finish.
  4. Firefox will open with all factory defaults applied.


Further information can be found in the Refresh Firefox - reset add-ons and settings article.

Did this fix your problems? Please report back to us!

This could happen if the security software (AVG, other) is scanning HTTPS. You may have to reinstall the root certificate via the security software interface after exiting Firefox, or Import it into Firefox via Tools (Alt + T) > Options > Advanced > Encryption > View Certificates > Authorities. You can also try to check by temporarily disabling HTTPS/SSL/Secure scanning in the security software.

Can you give me more info on importing certificates (how to get them) and disabling those things. I'm not familiar with all the above.

Please see this.

Configuring AVG

The AVG forum would also be helpful.

Some firewalls monitor secure (https) connections and send their own certificate instead of the website's certificate.

You can retrieve the certificate and check details like who issued certificates and expiration dates of certificates.

  • Click the link at the bottom of the error page: "I Understand the Risks"

Let Firefox retrieve the certificate: "Add Exception" -> "Get Certificate".

  • Click the "View..." button and inspect the certificate and check who is the issuer.

You can see more Details like intermediate certificates that are used in the Details pane.

Some examples are ESET and Bitdefender.

  • ESET setup -> advanced setup -> extend web and email tree -> SSL
  • SSL protocol: Do not scan SSL protocol
  • BitDefender -> Privacy settings -> disable Scan SSL

I give up -_-

Did you try to retrieve and inspect the certificate like I posted above?

Can you attach a screenshot that shows the details of such an certificate?

Use a compressed image type like PNG or JPG to save the screenshot.
