Disabling cookies on a browser can enhance privacy by preventing websites and advertisers from accessing personal data, reducing behavioral tracking, and limiting targeted ads. While cookies are designed to improve user experience by remembering actions, preferences, and login sessions, they are also used for advertising and analytics, potentially compromising user privacy. Blocking third-party cookies can prevent tracking across different sites, although this may affect certain website functionalities that rely on these cookies. Users can manage their cookie settings to regain control over their data storage across websites, and cookies can be re-enabled if desired. Bhavya Hada, an experienced software testing and quality assurance professional, provides insights into managing cookie settings and emphasizes the balance between privacy and web functionality.
