Google developer Devlin Cronin[commented](https://chromium-review.googlesource.com/c/chromium/src/+/7813942?tab=comments)on the Chromium commit calling for the removal of the last references to Manifest V2, explaining:
> MV2 extensions are no longer allowed in any supported version of Chrome, and we are removing support for them and the associated functionality\. We won’t be able to provide / maintain this functionality indefinitely due to the complexity and tech debt, as well as the security risks it entails \(we’ve actually found a number of bugs that are specific to MV2 lately\)\. Of course, other browsers can continue supporting these if they so desire\.

Google Chrome's transition to Manifest V3 removes the final loopholes for Manifest V2 extensions, effectively ending support for popular ad blockers like uBlock Origin by June 2026.
Google Chrome is enforcing Manifest V3, which disables workarounds for ad blockers like uBlock Origin, and Microsoft Edge and Opera are expected to implement similar restrictions.
This academic paper empirically investigates whether Google's transition from Manifest V2 to V3 in Chrome reduces ad blocker effectiveness, finding no statistically significant degradation and even slight improvements in anti-tracking for MV3 ad blockers.
This article explores options for replacing the deprecated uMatrix browser extension under Chrome's Manifest V3, proposing a solution using declarativeNetRequest and Content Security Policy to control site permissions and subresource requests.
Google published exploit code for an unfixed Chromium vulnerability that can turn browsers into a limited botnet, affecting Chrome, Edge, and other Chromium-based browsers. The vulnerability remains unpatched after 29 months.
