^Ditto. Same thing as of 13th of Sept-2015. Edge works fine, Firefox needs https scanning disabled.
I removed chrome on my setup because, for some weird reason(s), it or something else that used it, kept creating cookies(chrome cookies) without me USING chrome at all.
I think this started after I installed Win10, but I'm not sure. (Chrome)... (no phantom cookies since then, 1 week)
