Firefox not updating

To use Firefox's Network Security tab: Special thanks to Steve Gibson and Leo Laporte for mentioning the Calomel SSL Validation Firefox add-on in "Security Now" Episode 428, "Security Now" Episode 430 and "Security Now" Episode 431. In order for the add on to rate a site at 100%, the site must prefer strong, 128 or 256 bit Perfect Forward Secrecy (PFS) TLS v1.2 ciphers and use certificates hashed with at least ECDSA or RSA SHA-256 @ 2048 bit key size.

Using this site as an example, notice our server prefers a Galois/Counter Mode (GCM), Elliptic curve Diffie-Hellman Ephemeral (ECDHE) and Advanced Encryption Standard (AES) cipher with at least 128 bits.

There you will see the "Calomel SSL Validation" button in gray. We like the placement to the left of the URL bar, but the position is completely up to you.

You may need to refresh the page for the icon to turn the correct color after the install.

If the certificate authority reports a problem with the cert, the cert is invalid or the user can not independently verify the cert then we can not trust it.

The button will change color depending on the grade from red (low score), to yellow, to blue and finally to green (high score).

Standard HTTP unencrypted connections will turn the toolbar icon gray as will any blank tabs.

This means that Comodo SSL only verified that the owner of the domain, that is us, bought the cert for

A DV class certificate is a very simple and fully automated verification process done by the certificate authority (CA) and is good enough for 99% of web sites.
