Ignoring Frame Navigation - Foulest/Osprey GitHub Wiki

By default, Osprey ignores frame navigations when you browse the web due to false positives. Frame navigation refers to different URLs being loaded on a website in the background (i.e., Google Analytics links in the background of a web page, or CAPTCHA elements that originate from different websites, such as https://hcaptcha.com). False positives can occur with this extra-strict URL checking. For example, one or more providers may block the entire page due to a false detection of an advertising element, a CDN network, or a third-party analytics tool. It's not recommended for most to have it enabled.

If you want to disable ignoring frame navigation and have Osprey check every URL loaded by a website, here's how:

1. Right-click Osprey's icon in your extension toolbar.
2. Click the Ignore frame navigation setting in the context menu.

You can test frame navigations being detected by visiting this test page with Microsoft SmartScreen enabled.
