Google Reverses Decision: Keeping Third-Party Cookies in Chrome
In a surprising turn of events, Google has announced that Chrome browsers will continue to support third-party cookies. This decision comes after years of planning to phase them out in favor of more privacy-focused alternatives. The tech giant’s sudden reversal has sent waves through the digital advertising industry and raised new questions about the future of online privacy.
The Unexpected U-Turn
Google first announced plans to eliminate third-party cookies from Chrome in 2020. The company set an ambitious timeline to phase them out completely by 2022. However, Google pushed back this deadline multiple times. The most recent timeline suggested cookies would be gone by the end of 2025. Now, Google has scrapped these plans entirely.
According to Google’s announcement, third-party cookies will remain active in Chrome for the foreseeable future. The company cited “ongoing challenges with alternative technologies” and “industry feedback” as key reasons for this reversal. This represents a major shift in Google’s stated privacy roadmap for its dominant web browser.
What Are Third-Party Cookies and Why Do They Matter?
Third-party cookies are small text files that websites place on your browser. Unlike first-party cookies (placed by the site you’re visiting), third-party cookies are placed by other domains. They track your activity across different websites and build detailed profiles of your browsing habits. Advertisers use this data to target you with personalized ads.
These cookies have been essential to the digital advertising ecosystem for years. They help marketers track campaign performance and target specific audiences. However, they’ve also raised serious privacy concerns. Many users feel uncomfortable with the level of tracking these cookies enable.
The Privacy Implications
The continued use of third-party cookies raises important privacy questions. Most users don’t realize how extensively their online activities are tracked. This tracking happens across websites, creating detailed profiles of interests, shopping habits, and even personal information.
Privacy advocates have long criticized cookies as invasive. This is why competing browsers like Firefox and Safari already block third-party cookies by default. Google’s decision to maintain support for these tracking tools stands in stark contrast to the industry’s general movement toward greater privacy protections.
Why Google Changed Course
Google’s reversal wasn’t made in isolation. Several factors likely contributed to this significant policy change:
Advertising Revenue Concerns
Google’s business model relies heavily on advertising. The company generated over $237 billion in ad revenue in 2024 alone. Third-party cookies play a crucial role in this ecosystem. Without effective alternatives in place, removing cookies could seriously impact Google’s core business.
Many advertisers expressed concerns about the proposed alternatives. They worried that new solutions wouldn’t provide the same level of tracking and targeting capabilities. These industry pressures likely influenced Google’s decision to maintain the status quo.
Technical Challenges with Privacy Sandbox
Google’s proposed alternative, the Privacy Sandbox, has faced significant implementation challenges. This initiative aimed to create new technologies that would balance privacy concerns with advertising needs. However, the development process revealed unexpected complications.
Key components of the Privacy Sandbox, such as FLoC (Federated Learning of Cohorts) and Topics API, received mixed feedback from both privacy advocates and advertisers. Neither group seemed fully satisfied with the proposed solutions. Additionally, regulators raised concerns about Google potentially gaining even more market power through these new technologies.
- FLoC faced criticism for potentially creating new privacy risks
- Topics API provided less granular targeting than advertisers wanted
- Trust tokens and other proposed technologies proved difficult to implement effectively
Regulatory Pressure
Google faces ongoing antitrust scrutiny around the world. Regulators expressed concerns that removing third-party cookies might further strengthen Google’s dominant position in digital advertising. The UK’s Competition and Markets Authority (CMA) has been particularly active in monitoring Google’s plans.
By maintaining support for third-party cookies, Google may be attempting to avoid additional regulatory challenges. This decision could help the company argue that it’s not using privacy as a shield to further entrench its market position.
Industry Reactions
The announcement has generated mixed reactions across the digital ecosystem:
Advertisers and Ad Tech Companies
Many advertisers have expressed relief at Google’s decision. Third-party cookies provide valuable data for targeting and measurement. Ad tech companies that built their businesses around cookie-based tracking can now continue their operations without major disruption.
The Interactive Advertising Bureau (IAB) cautiously welcomed the announcement. However, they also emphasized the need for the industry to continue developing more privacy-friendly alternatives. Despite this reprieve, most industry leaders recognize that the long-term future still requires better privacy solutions.
Privacy Advocates
Privacy groups have harshly criticized Google’s reversal. Organizations like the Electronic Frontier Foundation (EFF) expressed disappointment, suggesting that Google prioritized profit over user privacy. They argue that Google had ample time to develop alternatives and failed to follow through on its commitments.
These advocates point out that other browsers managed to block third-party cookies while maintaining functionality. They question why Google, with its vast resources, couldn’t achieve the same result.
What This Means for Internet Users
For average Chrome users, this decision means business as usual—but that’s not necessarily good news for privacy. Your online activities will continue to be tracked across websites through third-party cookies. Advertisers will maintain their ability to build detailed profiles of your interests and behaviors.
If privacy is a priority for you, consider these options:
- Switch to browsers that block third-party cookies by default, like Firefox or Safari
- Use Chrome’s existing privacy settings to manually block third-party cookies
- Install privacy-focused extensions that limit tracking
- Consider using a VPN service for additional privacy protection
The Future of Web Privacy
Despite this setback, the push for greater online privacy continues. Apple and Mozilla have shown that browsers can function well without third-party cookies. Market pressure and evolving regulations will likely push Google to revisit this issue in the future.
The EU’s General Data Protection Regulation (GDPR) and similar laws worldwide have already changed how websites handle user data. These regulations will continue to evolve, potentially forcing changes that Google seems reluctant to make voluntarily.
Alternative Technologies
Even with this reversal, work continues on privacy-preserving advertising technologies. Several promising approaches are in development:
- First-party data strategies that rely on direct relationships with users
- Contextual advertising that targets based on content rather than user profiles
- Privacy-preserving machine learning techniques that keep personal data on devices
Major advertisers have already begun investing in these alternatives. They recognize that the industry must eventually move beyond third-party cookies, regardless of Google’s current position.
Looking Ahead
Google’s decision to maintain third-party cookie support in Chrome represents a significant pause in the web’s privacy evolution. However, it’s unlikely to permanently stop the momentum toward a more privacy-conscious internet.
Users increasingly demand better privacy protections. Competing browsers have demonstrated that alternative approaches are viable. Regulatory pressure continues to mount globally. These forces will shape the future of web privacy, with or without Google’s leadership.
For now, Chrome users should be aware that their online activities continue to be tracked through third-party cookies. Those concerned about privacy should explore alternative browsers or additional privacy tools.
The Bottom Line
Google’s reversal on third-party cookies highlights the complex balance between privacy, advertising effectiveness, and business interests. While this decision maintains the status quo for now, the broader trend toward enhanced online privacy continues. Both users and businesses should prepare for a future where traditional tracking methods will face increasing limitations, even if that future has been temporarily delayed.
