When I visit a website that requires PKI client certificates Firefox will allow the user to select which certificate to present.

How do you present a different PKI client certificate to a server once you have already presented one, in Firefox?

This blogpost describes what you are looking for:

To clear your SSL session state in Firefox choose History -> Clear Recent History... and then select "Active Logins" and click "Clear Now". Then the next time you connect to your SSL server Firefox will prompt for which certificate to use.

Since this was the highest result on google:

The location seems to have been changed (Tested on Firefox 101). You can now find the setting in:

Options > Privacy & Security > Security > View Certificates... > Tab Authentication Decisions.

Here you can remove every single decision for the selected client certificate.

And just for completeness, as i was searching for the easy way, without deleting everything:

  • Open the specific url
  • Click on the certificate information next to the url (The Lock-Sign)
  • You can directly click on Delete Cookies and Website Data
  • Select the specific (sub-)domain you want to reset
