I logged out of FR completely and closed the browser. Opened browser and went to log-in page for FR. To the right of the fields for user name and password, there’s a dropdown menu with “convenient”, “secure”, etc.
There may be an easier way, but that’s how I did it. (Nothing changed, though. Still “not secure”.)
That is weird.
The word ‘secure’ on the log-in page has nothing to do with the site being secure. Look up HTTPS on Wikipedia.
