WHEN I TRY TO CONNECT FB BELOW ERROR MSG APEARS This Connection is Untrusted

You have asked Firefox to connect securely to www.facebook.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.

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.

www.facebook.com uses an invalid security certificate.

The certificate expired on 31 December 2015 17:30. The current time is 10 January 2016 23:32.

(Error code: sec_error_expired_certificate)

Note: Windows users should download the ‘’’active_x’’’ for “Internet Explorer,” and the ‘’’plugin’’’ for “Plugin-based browsers” (like Firefox).

Note: Windows 8 and Windows 10 have built in flash players and Adobe will cause a conflict.
