11 JavaScript Window variables

These are the non-standard variables defined on the window object. These include var declarations and global functions and can be helpful in identifying possible client-side frameworks and code.

1 Cookies

Cookies are little pieces of information stored in the browser of a user. Whenever a user visits the site again, he will also send his cookie values, thus allowing the website to re-identify him even if he changed locations. This is how permanent logins work.

12 Console Messages

A page may trigger messages to the console to be logged. These are often error messages about being unable to load a resource or execute a piece of JavaScript. Sometimes they also provide insight into the technology behind a website.

Source	Level	URL Text
security	warning	Message: Error with Permissions-Policy header: Origin trial controlled feature not enabled: 'browsing-topics'.
security	warning	Message: Error with Permissions-Policy header: Origin trial controlled feature not enabled: 'interest-cohort'.

other	error	URL: http://catalog.loc.gov/ Message: The Cross-Origin-Opener-Policy header has been ignored, because the URL's origin was untrustworthy. It was defined either in the final response or a redirect. Please deliver the response using the HTTPS protocol. You can also use the 'localhost' origin instead. See https://www.w3.org/TR/powerful-features/#potentially-trustworthy-origin and https://html.spec.whatwg.org/#the-cross-origin-opener-policy-header.

Update your headers to uniformly request origin-keying for all pages on the origin.
