In Thunderbird, i went to Preferences » Privacy and Security » Manage
Certificates » Authorities and selected "COMODO RSA Certification
Authority".

Then i clicked "View".  in the viewer, there are different attributes of
the X.509 certificate.  Two of those attributes ("Basic Constraints" and
"Key Usages") have an empty square box to the left of the attribute name
(see attached picture).
