Google to remove Manifest V2 Chrome extensions on August 31

Google will remove all remaining Manifest V2 Chrome extensions on August 31, according to 9to5Google. The move caps a deprecation effort stretching more than four years and forces a final shift to Manifest V3. It matters because users and developers relying on V2 APIs must migrate or lose functionality and support.

9to5Google adds that Google is completing the four-year transition after prior pauses, and that Manifest V2 add-ons will no longer run on Chrome once the cutoff arrives. Developers face a compressed window to ship Manifest V3 updates, and users may see older tools stop working if no replacements land in time. Watch for Google to publish rollout specifics across Chrome channels and for major extension makers to push updates ahead of August 31. [Developing. This article will be updated.]
