I have a PAC file being used with WSS (Web Security Service). We need to mention the egress IP on the WSS portal while using PAC file. If the egress IP is not mentioned and we are using a PAC file we get a Captive portal page. This is how the WSS with PAC file works. This works fine on Chrome and Egde. I do not have any PAC file configured on the Firefox proxy settings. As soon as I launch Firefox, I start to get the captive portal login page on all the browsers (Chrome, Egde, Firefox). As soon as I close Firefox, and refresh the other browsers, everything starts to work again. So it looks like, Firefox is disrupting the internet connection as soon as we launch it. Please help!
