Firefox is about to label non-Https sites as insecure
 

By default

Firefox browsers might soon indentify sites which do not run HTTPS as insecure.

The current Firefox Nightly Edition (version 59) includes a secret configuration option that when activated will show a visible visual indicator that the current page is not secure. There is a hidden preference named "security.insecure_connection_icon.enabled" that when enabled will show the above strikethrough lock icon on all HTTP pages.
