My experience with similar problem did result from the Firewall I was using asking for permission via popup, the only problem was I could not see the popup because it was underneath the SafeZone Browers, I only discovered this by accident when I shut down SafeZone quickly and discovered the popup still visible,
Once I gave permission and to 'Remember' all was fine.

Just an experience, not sure it any relevance to your situation
