Google Chrome, developed by Google, has become the most popular web browser since the early 2010s, surpassing Microsoft's Internet Explorer and contributing to the decline of Mozilla Firefox. As an extension of Google's vast advertising network, Chrome's privacy and security features draw significant scrutiny, especially regarding the handling of user data. Google plans to replace third-party cookies with its Privacy Sandbox by 2024, a move that has sparked controversy due to its delayed implementation compared to competitors like Safari and Firefox. The Privacy Sandbox introduces APIs designed to balance user privacy with interest-based advertising, including the Topics API, Protected Audience API, and Attribution API. Additionally, Chrome's security features include Enhanced Safe Browsing, a built-in password manager, and HTTPS enforcement, all aimed at enhancing user protection but also raising concerns due to Google's dual role as a major advertising entity. While Chrome regularly updates its security features, privacy advocacy groups often recommend more privacy-focused browser alternatives. Users of Chrome can enhance privacy and security through custom settings and extensions, acknowledging the inherent trade-offs of using a browser from a leading advertising company.
