I guess this solved it; I got to the Firefox news.

Where did you click "Firefox News" ?

Does it help if you change the protocol from https to http ?

https://blog.mozilla.org/blog/2012/08/28/firefox-for-android-gets-speedy-and-powerful-upgrade-for-tablets/ This is the site I was trying to get to when I got the error message. Both of the links above gave me the same error message. It is not a big deal just wondering why I get an unsafe message here.

Question owner

I made a mistake on my earlier question. I meant Mozilla News.

You may have a problem with an intermediate certificate that Firefox has stored.

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.

If that didn't help then remove or rename secmod.db (secmod.db.old) as well.

Question owner

No this did not solve it.

"blog.mozilla.org uses an invalid security certificate.

The certificate is only valid for blog.mozilla.com"

This is the technical info I get on the page.

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.

Thanks
