0 JavaScript Global Variables

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

0 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.

1 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: Unrecognized feature: 'bluetooth'.

Security Headers

This page lists any security headers set by the main page. If you want to understand what these mean and how to use them, head on over to this page

Header	Value
Content-Security-Policy	default-src 'self'; script-src 'self' 'unsafe-inline'; style-src 'self' 'unsafe-inline';

X-Content-Type-Options	nosniff
X-Frame-Options	SAMEORIGIN
