99% of all sites I get message "Secure Connection Failed", The page you are trying to view cannot be shown because the authenticity of the received data could not be verified.

How do I stop this? It started when I updated firefox a couple months ago. This issue makes me leary of updating it again

What are the exact error messages? More should be listed beside "Secure Connection Failed".

Diagnose Firefox issues using Troubleshoot(Safe) Mode {web link}

A small dialog should appear. Click Start In Troubleshoot(Safe) Mode (not Refresh). Is the problem still there?
