United States browser update ends legacy ad blockers

Google has confirmed it will fully remove Manifest V2 support from the Chromium codebase, ending functionality for many legacy ad-blocking extensions such as uBlock Origin. The change will take effect with Chrome 150, scheduled for release at the end of June 2026, concluding a multi-year transition to Manifest V3. Under Manifest V3, extensions face stricter limits on how they can intercept and modify network traffic, which developers say undermines traditional, highly efficient ad blocking. Once Chrome 150 is deployed globally, users dependent on Manifest V2-based tools will need to switch browsers, adopt alternative tools, or accept standard web advertising practices.
