[Home] ↣ [Privacy Protections Tests] ↣ [HTTPS Upgrade Loop Protection]
This test will navigate to page on a https upgradable domain that immediately redirects to its http version. This will cause a http↔http loop (client trying to upgrade, page downgrading). Clients should detect this scenario and allow page to load.
If the loop protection works the reported url will be "http:" and not "https:".
