Browser makers have continued tightening default restrictions on third-party cookies — small files historically used to track browsing activity across different websites for advertising purposes. The shift has been unfolding gradually over several years rather than as a single cutover.
What's changing
Rather than blocking third-party cookies outright, several browsers have moved toward more granular, permission-based tracking controls, alongside alternative technologies designed to support advertising measurement without individual-level cross-site tracking.
Why it matters for everyday users
For most people, the practical effect is fewer ads that seem to "follow" them across unrelated websites, and less cross-site tracking overall. Advertisers and publishers, meanwhile, continue adapting their measurement approaches to rely less on individual tracking and more on aggregated or on-device signals.
