Greetings. I recently upgraded to Windows 11 and started using Firefox again. In order to be more secure and private I am reviewing all of my settings everywhere. I am concerned that the security certificates that are currently in my Firefox are safe, secure and current. I know the internet is worldwide and bad actors can from any country but when I see them from certain countries that does concern me. Is there a way to verify the certificates are good? Is there an harm in deleting certificates? Is there any suggestions of what countries, websites to stay away from concerning certificates? If the validity is expired should I delete it? I do not like to make assumptions. I try to make informed decisions. Thank you, bkh8611@gmail.com
