Why Manifest V3 Compliance Is Critical
Google phased out Manifest V2 in 2024. All new and existing extensions must use Manifest V3 or face removal from the Chrome Web Store. We build exclusively to MV3 standards.
Manifest V2 (Deprecated)
- Background pages (persistent memory leak)
- Broad remote code execution permissions
- Blocked by Chrome Web Store since June 2024
- Potential security vulnerabilities
Manifest V3 (Current Standard)
- Service Worker (better performance)
- Declarative Net Request (faster ad blocking)
- Required for Chrome Web Store submissions
- Enhanced user privacy and security model
