i have used a website for years, now I get an untrusted connection warning. How do I progress?

Using FF 9.0.1 www.corp.delaware.gov gets me a "Connection Untrusted" note. Error code : ssl_error_cert_domain. Never happened before. Just used my wives desktop and it went through normally.

Rename the file cert8.db to cert8.db.old in the Firefox Profile Folder to remove all intermediate certificates that Firefox has stored by visiting secure websites.
If that helped to solve the problem then you can remove the renamed file cert8.db.old unless you have user certificates that you may want to export first and import them in the new file.
Otherwise you can restore the certificates by renaming (copying) the file back to cert8.db
Firefox will automatically store new intermediate certificates when you visit websites that send them.

Thanks, it worked
