100M+
users impacted by Chrome's Manifest V3 transition
More than 100 million users of major content-blocking extensions on Chrome have been affected by the Manifest V3 transition, which removed APIs that some legacy blockers relied on.
Context
Modern, MV3-native blockers (including NovaBlock) deliver near-identical filtering quality using declarativeNetRequest. Some legacy blockers shipped reduced-functionality versions; users had to migrate.
Key takeaways
- Manifest V3 didn't end ad blocking, but it forced re-architecture.
- MV3-native engines retain the speed/privacy benefits with a smaller permission footprint.
