Google has officially abandoned its long-delayed plan to deprecate third-party cookies in Chrome. After years of postponed deadlines and failed alternatives, third-party cookies will remain in the browser indefinitely.

The Timeline of Delays

The cookie deprecation timeline shifted repeatedly: originally planned for 2022, it was pushed to 2023, then 2024, then 2025, and now cancelled altogether. Chrome remains the only major browser that accepts third-party cookies by default, and with roughly 65% market share, this decision has significant implications for web privacy.

Why the Privacy Sandbox Failed

Google's proposed alternatives -- first Federated Learning of Cohorts (FLoC), then Topics API -- both failed to gain industry acceptance. FLoC faced backlash from privacy advocates, regulators, and other stakeholders. The Topics API was criticized by Mozilla, the UK Information Commissioner's Office, and the UK Competition and Markets Authority for privacy vulnerabilities.

The Contrast with Apple

When Apple introduced App Tracking Transparency in 2020, giving users a simple opt-out mechanism, 96% of US users chose to block tracking. This statistic illustrates the gulf between what users want and what the advertising ecosystem delivers.

The Broader Landscape

Google now vaguely references "a new experience in Chrome" for informed cookie choices, but details remain sparse. Meanwhile, Meta's pay-or-consent model and cookie walls face increasing regulatory scrutiny. The proposed ePrivacy Regulation aims to replace the current ePrivacy Directive with stronger protections, and US federal privacy legislation continues to develop.
