Why do I keep getting error message saying Firefox cannot connect to sites?
Error message:
Server not found
Firefox can't find the server at onlineaccess.ncsecu.org.
* Check the address for typing errors such as
ww.example.com instead of
www.example.com
* If you are unable to load any pages, check your computer's network
connection.
* If your computer or network is protected by a firewall or proxy, make sure
that Firefox is permitted to access the Web.

A possible cause is security software (firewall) that blocks or restricts Firefox without informing you about that, possibly after detecting changes (update) to the Firefox program.
Remove all rules for Firefox from the permissions list in the firewall and let your firewall ask again for permission to get full unrestricted access to internet for Firefox.
