Manifest V3 was developed to address concerns surrounding security and performance for its predecessor - V2 could be exploited to create malware and obtain sensitive data. A year later, in January 2023, the browser will no longer run Manifest V2 extensions, and update support will also be cut off.

Why it matters: Google has revealed that its Chrome browser extensions that fall under the Manifest V2 framework will no longer work from January 2023, which could lead to ad-blockers being impacted or just outright ceasing to function.ĭevelopers will not be able to submit new Manifest V2 extensions on the Chrome Web Store come January 17, 2022, although they'll be able to update existing extensions in the interim.
