Extended Tracking Powers
Oleksii Starov, Nick Nikiforakis · 2017
Users have come to rely on browser extensions to realize features that are not implemented by browser vendors. Extensions offer users the ability to, among others, block ads, de-clutter websites, enrich pages with third-party content, and take screenshots. At the same time, because of their privileged position inside a user's browser, extensions have access to content and functionality that is not available to webpages, such as, the ability to conduct and read cross-origin requests, as well as get access to a browser's history and cookie jar.
