The list view used Edit::Preferences::Advanced::Encryption::View Certificates::Authorities for Firefox 2.0.0.15 on Ubuntu exhibits the same problem, so it's definately a platform problem. This problem has been fixed in FF3 though so compiling against the mozilla trunk XULRunner will likely be sufficient to fix this bug (this is itself of course not exactly a trivial thing to do I suppose).
