Data consent refers to the process by which individuals give their permission for companies to collect and use their personal information. To address concerns about data privacy and consent, various tools and methods have been developed. One such method is the use of browser extensions that allow users to manage their data consent preferences. These extensions provide users with greater control over how their personal information is collected and used by the websites they visit. Users can choose which types of data they are willing to share, or opt out entirely from certain forms of data collection. By giving individuals more agency in managing their own data consent, these browser extensions aim to empower users and protect their privacy. While browser extensions offer a practical solution for managing data consent on an individual level, there is also a growing call for federal regulation in this area. The revenue streams generated through the collection and sale of personal data have prompted concerns about its misuse and exploitation.
