Cannot import certificates

I am trying to import USG/DoD certificates in Firefox 23 on Ubuntu 12.04LTS. When I try to import them, it apparently goes well (no error messages) but they do not show up in the Certificate Manager. I have tried both the DoD Configuration Add-on (http://www.forge.mil/Resources-Firefox.html) and manually importing the root certificates (http://dodpki.c3pki.chamb.disa.mil/rootca.html), and the results are the same.

Chosen solution

The extension works fine for me on Linux.

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.

You can click the Update DoD Certs button in the window that opens if you click the Preferences of the extension on the about:addons (Firefox/Tools > Add-ons > Extensions) page.

If this didn't work then disable all other extensions in case some are interfering.

I renamed the cert8.db file in ~/.mozilla/firefox/*.default/ to the next directory up, then restarted FF. After I updated DoD Configuration with the "Update DoD Certs" button, the Certificate Manager now shows several dozen U.S. Government certificates, whereas before there were none.
