A problem with your browser?

A browser plugin, yes, that I installed to not go to insecure websites.

Does that really make the site insecure, though?

What’s the scenario, someone has launched an elaborate ARP cache attack in order to MITM a website about roads on Hawaii in order to get you mildly lost so that you have to pull over and look at Google Maps for directions, costing you an extra minute of travel time?

I understand your problem, I use similar filters. But I use a VPN too, so I'm able to quickly get around it.

Still, phrasing reads a bit like a BBQ review that starts out "as a vegan ..."

Why not?

I limit myself to https-only websites using website plugins. For privacy reasons.

You might want to consider using Tor Browser, since that mitigates more privacy issues than just using only https on websites.
