If your default browser is Firefox or Chrome you have have notice recently that both browsers are starting to take a harder stance on insecure login pages.
Whenever inputting text to a field, or when on a login page not secured with HTTPS, both Firefox and Chrome have their own ways of notifying users that the data they are sending, such as passwords or credit card numbers could be intercepted by someone bad.
Chrome is showing “Not secure” next to the URL bar and Firefox puts a banner under the password field of text boxes.
Users on twitter are seeing these notifications and taking it up with the companies that run the sites.
