The revision of the Chrome browser extension framework, which was first introduced in 2019, is being stressed by Google as solely an update to patch security issues. With full functionality at stake for plugin makers, Firefox creator Mozilla said it'll mostly adopt Manifest V3, but it won't replace the blocking webRequest API uBlock relies on with Google's alternative, declarativeNetRequest (DNR). He said the changes in the Manifest V3 proposal would effectively break the extension, which also operates as a content blocker.Īs The Register noted, Adblock Plus and other plugins that deliver an ad-free experience for users will still be able to function to an extent, but modifications may make it become a shadow of its former self the changes in V3 limit the abilities for extension developers. But it's not that straightforward for ad-blockers, at least in the case of Raymond Hill, developer of the hugely popular uBlock Origin.
Once Manifest V2 extensions are indefinitely blocked in Chrome, developers will naturally need to update their extensions to function under Manifest V3. "It is an evolution of the extension platform that takes into consideration both the changing web landscape and the future of browser extensions." "Years in the making, Manifest V3 is more secure, performant, and privacy-preserving than its predecessor," said David Li, product manager for Chrome extensions and the Chrome Web Store. 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.
