I use Opera so I hope I can help
As I see it, there are diff issues
LQ has a http protocol so if you get to it on your new system, the firewall is not the issue altho if you never could see LQ it is.
But most banks sites and Yahoo mail login, use https which is a firewall issue
open guarddog with root powers and allow http and https

2) also clear your history so you get a fresh page and close down opera b4 resetting firewall.
