** Firefox 68 ESR is the only version of Firefox that currently supports key generation. No later version will work. You can download Firefox 68 ESR here : https://ftp.mozilla.org/pub/firefox/releases/68.0esr/ 

You MUST use the exact same browser that you used to complete the Certificate Details part of your order. Chrome and Edge will not work, our order system would have forced you to use Firefox, real Internet Explorer (or Firefox on a Mac). Make sure that when you're following the instructions in this tutorial that you used Firefox. These instructions only apply to those that used Firefox to submit the certificate details portion of their order.

** IMPORTANT NOTE : You can only export your certificate *AFTER* it is issued and you've visited the collection link.

This tutorial covers Firefox version 61.0.2


To export a stored code signing certificate from Firefox to a PFX file follow these steps :


Click the Tools menu, then Options, then the Privacy & Security button/tab on the left side


Scroll all the way to the bottom, using the scroll bar on the right and click View Certificates.



Click the Your Certificates tab, locate *your* company name under the Sectigo group, and left-click it, then click the Backup button at the bottom


Firefox will prompt for the name of the certificate file and you may save it anywhere you would like with any file name you would like .

The final step is to set a password for the PFX file -- DO NOT FORGET THAT PASSWORD!

The file is portable and can now be copied to any computer. Additional Note : Firefox will save the file with a .p12 extension – that’s OK! Just rename the file to .pfx if you would like but you can use it with any code signing tool regardless of the file's extension.
