About MV2 Checker

MV2 Checker is a browser extension that helps you identify Chrome extensions using Manifest V2, which Google plans to phase out. This tool can help you prepare for future compatibility issues with your installed extensions.

Frequently Asked Questions

What is Manifest V2 vs Manifest V3?

Manifest V2 and V3 are different versions of Chrome's extension platform. Google is transitioning from V2 to V3 to improve security, privacy, and performance. Some extensions built for V2 may not work properly when Google fully deprecates V2 support.

Why should I care about Manifest versions?

Extensions using Manifest V2 may stop working correctly in future Chrome updates. This tool helps you identify which extensions might be affected so you can find alternatives or contact developers for updates.

How does this extension work?

MV2 Checker scans your installed Chrome extensions and identifies which ones are using Manifest V2. It operates entirely within your browser and doesn't collect any personal data.

Is this extension free to use?

Yes, MV2 Checker is completely free with no hidden costs or premium features.
