How do you remove the root CA certificate that fiddler installs

Question

Fiddler helpfully offers to add a unique root CA certificate to intercept HTTPS traffic.

Once this certificate has been added, how do you go about removing it?

Answer 1

Since Fiddler 4.6.1.5 the GUI is a bit different.

Go to Tools -> Fiddler Options -> HTTPS. Then click the "Actions" button and then "Reset All Certificates"

It will popup a message that it could take a while but it's really quick. Approve all popups and there you go.

Pay attention not to re-approve the certificate again (when I did it the message for approving the certificates popped up when I finished to approve all the popups.)
