Ever since the last update, I have been unable to access an HTTP site on my home network. Site does not have https setup. Site does require authentication. It my home network (so only accessible when I am home). Firefox immediately returns "HTTP ERROR 401 Unauthorized". How can whatever you turned on be turned off so that I can resume using Firefox (instead of Safari, which doesn't have this issue)? If your answer is "setup https", that's not what I'm asking (remember I said this was on my home network, so only accessible when I am at home).
