I was able previously to access my webmail email server (https://webmail.centurylink.net/) but Firefox is now completely blocking my access. The details I get back from Firefox is:
Secure Connection Failed
The page you are trying to view cannot be shown because the authenticity of the received data could not be verified.
What can you do about it?
The issue is most likely with the website, and there is nothing you can do to resolve it. You can notify the website’s administrator about the problem.
Error Code: PR_CONNECT_RESET_ERROR
Why? If I want to go to a site that is MY business not Firefox's
Turned out that it is my crappy connection speeds courtesy of my ISP. My nominal 10MBpS was throttled back to 1.2MBpS. Now that it is back up to its normal 3.2MBpS connection is restored.
