I want to erase all certificate exceptions, that is, go back to the original default set of trusted SSL certificates. I've found the Certificate Manager and its big lists of trusted things, but I have no idea which of them ship with Firefox and which of them were added by me at some time in the past. How do I do this?

Rename or delete the file cert8.db in the Profile Folder to remove all intermediate certificates that Firefox has stored by visiting secure websites.

The build-in root certificates show as "Builtin Object Token" and the stored intermediate certificates as "Software Security device"

Rename or delete the file cert_override.txt (cert_override.txt.old) in the Firefox Profile Folder to remove all permanent exceptions that you have saved.
