I installed Comodo today. When Firewall Security is on safe mode, I cannot access sites, but receive this message:
The connection to the server was reset while the page was loading.
The network link was interrupted while negotiating a connection. Please try again.
When I disable Comodo Firewall, and use Windows firewall instead, all is fine.
For background: Windows XP, Firefox brower, Comodo 184.108.40.2061
