Hello, I’d like to receive some help related to a problem I have with mozilla when I import some electronic certificate to sign in documents in my laptop. I have an MacBook Pro with software macOS Mojave, version 10.14.6, and after downloading Mozilla Firefox, I have realized that after importing and install some electronic certificate issued by authorities to sign in documents, this dissapeared once I log out my computer. I’ve tried modifying the settings carry on the instructions I’ve found but settings go back like were before being modified, so I don’t know how to solve this to keep the settings modified once I’ve changed them. I’d be very grateful if you can help me with this matter. Looking forward to hearing from you. Alejandro.
