I am doing some experiences/investigation into captive networks/the WISPr protocol. (see Getting WISPr tags from a FON authentication portal )
However, the Captive Network Assistant, "Captive Network Assistant.app", in MacOS, that is opened once you login in a Captive Portal supporting WISPr, is getting into the way.
Considering it also opens spontaneously when logging into captive portals, I might actually want to disable it for good, as I use Firefox.
How might I do that in MacOS Sierra?
