WebKit2.WebView::insecure-content-detected

connect('insecure-content-detected', function (webView, event: WebKit2.InsecureContentEvent, ): void);
  

This signal is emitted when insecure content has been detected in a page loaded through a secure connection. This typically means that a external resource from an unstrusted source has been run or displayed, resulting in a mix of HTTPS and non-HTTPS content.

You can check the event parameter to know exactly which kind of event has been detected (see WebKit2.InsecureContentEvent).
