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 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 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.
Big Tech companies including Meta, Google, and Apple are collaborating with Mozilla on a new browser standard for advertising attribution, raising concerns about privacy and competitive advantages.
The article introduces CloakBrowser, an open-source stealth Chromium-based browser designed to bypass bot detection systems like reCAPTCHA and Cloudflare Turnstile. It claims to offer superior stealth capabilities by patching the C++ source code rather than injecting JavaScript, positioning itself as a free alternative to expensive commercial anti-detect browsers.
