Expired Chrome Extension Revival Kit: 4,777 Forgotten Gems

What if your next successful Chrome extension…had already been built?

Once upon a time, 4,777 Chrome extensions were live on the store - helping real users, solving real problems, and earning real ratings.

But when Google forced developers to upgrade to Manifest V3, thousands of these tools were abandoned, not because they failed - but because their creators moved on.

What’s left?
A goldmine of pre-validated, expired ideas, just waiting to be revived.

These aren’t random listings. Every single extension in this kit:

✅ Had 500+ users
⭐ Rated 3.5+ stars
🗳️ Reviewed by 10+ people
📅 Includes release & last update dates

You now have a roadmap to:

✅ Spot extensions users loved but lost
✅ Rebuild them with modern tech (MV3)
✅ Launch with confidence - because demand already existed
