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.

Why This Matters to You

Your favorite ad-blocker might stop working soon. Google's update will limit how extensions like uBlock Origin function. If you rely on these tools for a cleaner web experience, you may need to find alternatives or accept more ads.

The Bottom Line

Google's shift to Manifest V3 is a blow to traditional ad-blocking. It's a change that prioritizes web advertising over user control. If you're not ready to see more ads, start exploring other browsers or ad-blocking tools. Worth forwarding if you know someone who values a clutter-free web experience.
