Entering the http version of the Hotmail site URL, in Opera 12.14, I get a malware warning. Upon entering the https version of the Hotmail site URL, I get an auto-redirect to the https LiveMail's log-in page. In Firefox 33, the http version of the site auto-redirects to the https LiveMail log-in page. Obviously, there's some differences in how the site/browser interfaces are working for this.
