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

Question

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?

Answer 1

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.

Answer 2

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.
