Google Chrome is a staple for many users, both on desktop and Android devices. It's among the first applications installed on a new computer for good reason—its speed, efficiency, and feature-rich experience. However, a significant change is on the horizon that could impact many users, particularly those who rely on certain extensions. This change involves the transition from the Manifest V2 framework to the new Manifest V3, which may render existing extensions, such as popular ad blockers, obsolete.
Last year, Google announced the deprecation of Manifest V2 extensions in favor of the new Manifest V3 framework. The goal is to enhance user experience and improve security and performance. As of June 3, Google began rolling out warnings for Manifest V2 extensions across stable, dev, and Canary versions of Chrome. This update affects various extensions, including those used for ad-blocking.
Raymond Hill, the lead developer of uBlock Origin, explained that uBlock Origin depends on Manifest V2 definitions, which is why users are seeing warnings. Although this shift to Manifest V3 is intended to be beneficial, it has created challenges for users of older extensions.
For those who are concerned about the transition, there are some options available. The Chrome Web Store suggests alternatives such as uBlock Origin Lite, Ghostery, and Adblock Plus. uBlock Origin Lite is designed to comply with Manifest V3 but may lack some features found in the original version. Ghostery and Adblock Plus are also recommended for users looking for similar functionality. Chrome allows users to re-enable older Manifest V2 extensions temporarily, though this option will be phased out soon. By early next year, Manifest V3 extensions will be the only ones supported. If the new framework poses too many issues, users might consider switching to a different browser. For instance, Firefox does not plan to deprecate V2 extensions in the near future, offering an alternative for those who prefer to keep using their current extensions.
The transition to Manifest V3 will affect all Chrome users, with a full switch expected by early next year. However, enterprise users will have additional time until June 2025 before Manifest V2 is completely phased out. The move to Manifest V3 is designed to address several issues, including security and performance, but it also presents a challenge for developers and users of older extensions.

The shift to Manifest V3 represents a significant change in how Chrome extensions will operate. While it promises enhanced features and security, it also means that many current extensions, especially ad blockers like uBlock Origin, will need to be updated or replaced. Users should explore available alternatives, consider temporary workarounds, or switch to browsers that support older extension frameworks if needed. The transition will undoubtedly reshape the extension landscape, and staying informed will help users navigate these changes effectively.
