Identity solutions keep an audience addressable where no third-party cookie is set. Third-party cookies did not go away; they are missing on part of your traffic.
| Browser or program | Third-party cookies, October 2026 |
|---|---|
| Chrome | Still supported. In April 2025 Google kept its current approach, a user choice in Chrome settings, and dropped the planned standalone prompt. Incognito mode blocks them by default. |
| Privacy Sandbox | In October 2025 Google announced it is retiring most of its APIs, including Topics, Protected Audience and Attribution Reporting. CHIPS and FedCM stay. |
| Safari | Blocked by default since March 2020 (Safari 13.1, iOS 13.4). |
| Firefox | Total Cookie Protection by default since June 2022: each website gets a separate cookie jar, so a tracker sees behaviour on one site only. |
