I am new to firefox customization. I need help to understand, '''how firefox picks up CA certificates from the global ca-certificates path in ubuntu and uses them in their own cert9.db''' Currently, what I am trying is, If I have a rootCA certificate (which I generated using openssl), I want to keep it in a specific path, such that when firefox launches, it picks up that certificate and uses it. How can i achieve it. I have tried using the policies.json, which works. But are there any other ways to achieve it?
