I reinstalled Firefox because Facebook links weren't posting. Now, every website is untrusted (google, facebook, even Mozilla's web site).

So initially my problem was that with this computer, links to external sites could not be posted on facebook. This problem was individual to this computer, so I reinstalled Firefox. After reinstalling, every web site I visit is telling me that the connection is untrusted. Most people say to check your date and time, but mine are correct, and I made sure to sync it with one of the internet time sites windows gives as an option. I've used Mozilla for years, and it would kill me to have to switch because of this problem.

Try to rename the cert8.db file in the Firefox profile folder to cert8.db.old or delete the cert8.db file to remove intermediate certificates that Firefox has stored.

If that helped to solve the problem then you can remove the renamed cert8.db.old file.
Otherwise you can rename (or copy) the cert8.db.old file to cert8.db to restore the previous intermediate certificates.

Firefox will automatically store intermediate certificates when you visit websites that send such a certificate.

You can use this button to go to the Firefox profile folder:

I have tried this, but this has not resolved the issue. Also, for all https sites, if I accept the supposedly insecure certificate, nothing but basic html is present (no images or anything) despite settings being set to accept such.

Which security software (firewall, anti-virus) do you have?

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.
