Whenever I type in a URL, I don't usually bother to add http://www. in the URL. This has always worked for me up until a couple of weeks ago. Now, when I don't include this, the URL automatically switches to "https://www." format. For example, when I type "example.com" in the URL bar, it automatically makes the URL "https://www.example.com/". I do not have any add-ons or extensions installed that should cause this problem.
