How do I export my Code Signing Certificate from Firefox?

Once the validation is finished, the issuing Certificate Authority (CA) will send the certificate via email to the certificate requester. Using Internet Explorer or Chrome or Safari, as your browser and the same PC which generated the order, follow the “pick-up” or “collection” link in the email and initiate the downloading process. The in-browser script will automatically pull the previously stored private key from the browser’s file system and install it in your Certificate Manager folder.

Now, to receive the actual certificate, you must export the certificate and private key and save it to your PC/desktop as a PFX (.p12) file. Follow the detailed instructions below to navigate through the export process in Firefox
