I opened the Firefox browser today and I got this pop up saying I had to log in to the network to browse the internet. No webpage would opened #. Secure connection failed. The pop up go button opened some network portal web page and nothing else. I checked my control panel and found in my firewall that the connections for Firefox had been blocked. So I allowed the connections. In my Firefox browser I checked options - privacy and security- permissions - exceptions and found the same URL as the pop up "go" button/message had linked to. I cannot remember the name of this website. I deleted the exception. Then I reopened Firefox browser and I was able to connect to websites. Has this happened to anyone else ? What caused it and how did they turn of the rules for Firefox in my firewall ?
