Google is again delaying its plan to phase out third-party cookies in the Chrome browser, this time to the second half of 2024. 

The delay is all about ensuring web developers, publishers and advertisers have enough time to test and adopt Google’s alternatives to third-party cookies, which promise to help companies serve up relevant ads, without compromising users' privacy

“The most consistent feedback we’ve received is the need for more time to evaluate and test the new Privacy Sandbox technologies before deprecating third-party cookies in Chrome,” Google Vice President Anthony Chavez wrote in a blog post on Wednesday. 

Without the delay, Google fears marketing firms may resort to using more invasive web tracking technologies, such as browser fingerprinting, so that they can target users with relevant ads. “This deliberate approach to transitioning from third-party cookies ensures that the web can continue to thrive, without relying on cross-site tracking identifiers or covert techniques,” Chavez added.  

The problem with third-party cookies is how they can track your web browsing activities from one site to the next, giving advertisers a view into your personal habits. It’s why Mozilla’s Firefox and Apple’s Safari are already blocking third-party cookies by default. 

Google’s original goal was to phase out third-party cookies in Chrome by around late 2022, citing how users were demanding greater privacy through the browser. But the company’s alternatives to third-party cookies have been taking longer than expected to develop and gain traction.

A year ago, Google announced it had to delay phasing out third-party cookies to mid-2023, in order to secure support from both businesses and government regulators. Chrome has 65.8% share over the market. Hence, any change to the browser could affect millions of users, and numerous businesses everywhere.

The company is now pushing back the date to potentially late 2024. In the meantime, Google is preparing to expand public testing for its alternatives to third-party cookies, dubbed the Privacy Sandbox APIs, later this year. 

“Beginning in early August, the Privacy Sandbox trials will expand to millions of users globally, and we’ll gradually increase the trial population throughout the rest of the year and into 2023,” Chavez said. “Before users are added into the trials, they will be shown a prompt giving them the option to manage their participation. As the web community tests these APIs, we’ll continue to listen and respond to feedback.”

The company then plans on formally launching the Privacy Sandbox APIs in Q3 2023. One of these APIs plans on serving users relevant ads by using Chrome to determine a handful of topics you’re interested in, and then feeding a random one to advertising networks.

My Experience

I've been a journalist for over 15 years. I got my start as a schools and cities reporter in Kansas City and joined PCMag in 2017, where I cover satellite internet services, cybersecurity, PC hardware, and more. I'm currently based in San Francisco, but previously spent over five years in China, covering the country's technology sector.

Since 2020, I've covered the launch and explosive growth of SpaceX's Starlink satellite internet service, writing 600+ stories on availability and feature launches, but also the regulatory battles over the expansion of satellite constellations, fights with rival providers like AST SpaceMobile and Amazon, and the effort to expand into satellite-based mobile service. I've combed through FCC filings for the latest news and driven to remote corners of California to test Starlink's cellular service.

I also cover cyber threats, from ransomware gangs to the emergence of AI-based malware. In 2024 and 2025, the FTC forced Avast to pay consumers $16.5 million for secretly harvesting and selling their personal information to third-party clients, as revealed in my joint investigation with Motherboard.

I also cover the PC graphics card market. Pandemic-era shortages led me to camp out in front of a Best Buy to get an RTX 3000. I'm now following how the AI-driven memory shortage is impacting the entire consumer electronics market. I'm always eager to learn more, so please jump in the comments with feedback and send me tips.

The Best Tech I've Had:

  • My first video game console: a Nintendo Famicom
  • I loved my Sega Saturn despite PlayStation's popularity.
  • The iPod Video I received as a gift in college
  • Xbox 360 FTW
  • The Galaxy Nexus was the first smartphone I was proud to own.
  • The PC desktop I built in 2013, which still works to this day.
