Lookyloo is a web interface that captures a webpage and then displays a tree of the domains, that call each other. This add-on allows to easily capture the URL of the current tab.
Additionally, the user can send the User-Agent of the browser, the referrer of the current page, and all the cookies of the current session to a lookyloo instance for a capture.
This add-on should only be used with a self-hosted lookyloo instance and never on a public instance (especially if you submit the cookies), as anyone using the instance will have access to the cookies and they could be used to login on websites.
If you want to use Lookyloo safely, please use the demo interface.
