Can't open unsecure self-hosted page #869
Description
I set up duckdns and have a small app that runs on a Pi, i can access my http-only page from Firefox, but not in Zen, the last thing that I see in the Browser console is "HTTPS-First Mode" trying to change http to https, but that happens in Firefox too, it should fail gracefully.
I am sure that the HTTPS-only option is disabled (besides, it would trigger a different warning, I tried to specify http:// at the start of the address but it made non difference, nor did it adding the website to the exception list for HTTPS-only: it will try to upgrade it regardless, which would not be too much of an issue if then it could still open it over http.
