Labeling HTTP as insecure is just plain wrong. I would beg to differ, sometimes HTPS is more insecure than HTTP: think of Hearthbleed bug that made servers with HTTPS vulnerable or certs that shouldn't be trusted, or the day when all LetsCrypt users were vulnerable, etc. Also you will loose a lot of ad-money. Of course Google with their search monopoly wants HTTPS because they profit from it. It's sad that Mozilla is influenced by some lobbyist. Well hopefully the popular forks on Linux distros remove that stupid warning label.
