This question has been asked before but never a satisfactory answer. I’ on my home lan. Then router has an embedded web server that is required to admin the box. The web server does not implement ssl. When I enter the router’s ip into FF - 192.169.1.1 - it gets changed to https://192.168.1.1. There is, of course, no such beast so I can never contact the router. This is a new - and very unhelpful - behavior in FF. There absolutely needs to be a way to disable this “feature” or to provide a whitelist where sites (like my router) can be entered and which FF will not mess with. I hope I’ve made this clear enough that no one is going to tell me that I need to reconfigure my web server to allow http or to do anything else that is impossible with an inherently insecure server embedded in firmware.
