Given that code signing certificate expirations are a problem for add-ons:

  • As a user, how do I view the list of code signing certificates my browser trusts for add-ons, with their expiration dates and trust chain?
  • As a user, how do I view the signing certificate chain for each of my installed extensions?
  • As an extension developer, what do I need to do when a certificate that was used to sign my extension expires?

(If, for any of the above questions, the simple answer is “there is no UI in Firefox to do this”, then I want to know the complicated answer, namely, in which files/databases/etc these are stored, in which data formats, and which existing third-party tools can be used to view them.)

Hi yurikhan, I don't know whether the Certificate Manager on the Preferences page lists the relevant certificate.

Perhaps the question would be better address to the Add-ons team over on their forum, at least to identify which certificate we would be looking for:

https://discourse.mozilla.org/c/add-ons

I think there would be at most a few certificates because the signing process runs through the Mozilla Add-ons site submission process, the developers do not apply their own certificates.

The certificate of a signed extension is in the Mozilla.rsa file in the META-INF folder.

Example of the certificate extension:
