Don't know if it's a recent modification to my browser set up but the web site addresses that appear across the top of my browser now have an (i) indicator against them if you click on that the message comes up.
I'm using windows 10.
It just rattled me for a moment, but most web sites seem to have this against them, except the serious stuff which have the green padlock.
I have noticed that some sites such as M&S only have the (i) indicator, but if you go to buy something, then the padlock appears.
Red warnings also appear if the site is considered unsafe.
Guess I'm just getting extra edgy about internet security these days.
Happy Christmas.
