To inform you about your own third-party exposure on the web pages you visit through a third party exposure score.
Third-party ("3rd-party") exposure is quite an important component of the more general concept of privacy exposure.
In the scope of uBO-Scope, "3rd-party" is defined as follow:
A network request to a remote server which has a different base domain name than the base domain name of the URL in the address bar is deemed "3rd-party".
A 3rd-party exposure score is derived not only from the number of distinct third parties on a web page, but also from the ubiquitousness of each of these distinct third parties.
