Help! I need to change my Security codes from SHA 1 to SHA 2

more options

How do I do this? All of a sudden, none of my regular sites are working because they still use SHA 1. I'm an amateur, but I know there will be a migration to use of SHA 2. How do I replace SHA 1 with SHA 2? Thanks!

I'm not sure I understand. Are you responsible for buying new secure certificates for the websites, or do you need a workaround so Firefox will still work with the existing site certificates?
