3 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.

undefined| event object| fence object| sharedStorage

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	error	URL: https://readbuf.pages.dev/ Message: Subresource Integrity: The resource 'https://readbuf.com/css/main.min.20fc31ca7258803442a28764fb1483016f366748b12153338a48283bc322b46d.css' has an integrity attribute, but the resource requires the request to be CORS enabled to check the integrity, and it is not. The resource has been blocked because the integrity cannot be enforced.
