For several months now, folks around the web have been posting about a problem with Facebook pages beginning to load but then freezing up. Many, including me, discovered if the Norton Smart Firewall was turned off, the problem went away. But I can't think of a worse website than Facebook to turn off your Smart Firewall to access. In a Norton Community thread Smart Firewall interferes with Facebook website some have been discussing it. Initially, I had concluded: There are many posts on numerous websites about this problem which is - some of the time but not always, you cannot use Facebook on a Windows device using Norton - the problem widely exists regardless of the browser used. The problem exists on all my Windows 10 computers all of which use the Norton Security Suite provided by Comcast. The problem does not exist on my Android and iOS devices using my network. So it has nothing to do with the network itself. If you turn off Norton Smart Firewall - which action as I understand it turns off the Windows Firewall - the problem goes away. If you uninstall Norton and use the Windows Firewall, the problem goes away. Therefore the problem is the Norton Smart Firewall. Norton, working with Facebook, needs to figure it out and fix it. But someone yesterday recommended turning off IPv6 in Firefox. So I tried that and didn't seem to experience the problem. But then today I was using the Microsoft Edge browser and ran into the problem. So I turned off the IPv6 protocol on my computer's Network Adapter. The problem went away. So if you switch off your IPv6 protocol, the problem with Facebook on Windows computers disappears. The problem is not browser-specific. And as an alternative you can your switch off your Norton Smart Firewall. If anyone has any thoughts about this I'd like to hear (see) them. As I posted in the Norton Community given those parameters I'm glad I'm not the person looking for the cause of the problem.
