Thank you developer (y)

Using pages that use self signed certificates it does insert WRONG whitelists (no SSL).

Of cause, because of let's encrypt a.o. most sites can skip this, but domains as "fritz.box" or intern IP do not work.

In my case "fritz.box" does redirect to http whereas https is possible but an incorrect certificate.

Here it would be nice to have an option in the settings to allow incorrect certs and let the user choose if he lieves the site.
