When I try to login to this site using FF, I get a "Revocation information invalid for this security certificate.". The same site and security certificate works fine in IE 8.

The reason it works fine in IE8 is because it uses a different security checking method than FF. Which site are you talking about?

The security certificate is from Comodo and has been working fine for years until I upgraded to FF15.

The site is posted in More System Details...

Try to remove the currently stored AddTrust AB -> COMODO SSL CA intermediate certificate in thee Certificate Manager.

That didn't help. I still get the warning about missing revocation information.

On the left is from

orange Firefox button or classic Tools menu > Options > Advanced > Encryption

On the right is the site's certificate, displayed by clicking the padlock icon next to the URL > More information > View Certificate > Details tab


The "More system details" is a link next to your original post.

Mine looks just like the image you posted. I ran validation on it before I posted here. I've also deleted and reinstalled the security certificate. While writing this post, I realized that I haven't tried it with all my add-ons disabled. I'll do that and post the results.
