MV2 Checker – Will your extensions survive June 2025?

About

Stop the surprise before it happens.
Chrome is phasing out Manifest V2 right now. When the final switch flips, any extension that hasn’t upgraded to Manifest V3 will be automatically disabled—including some of your favorites.

MV2 Checker gives you a one‑click health report:

Instant scan – Lists every installed extension still on Manifest V2.
Clear status – Green “All good!” screen if you’re safe; bold yellow warning if you’re not.
Smart links – A “Find MV3” button next to each risky add‑on opens the Chrome Web Store search for you—no hunting.
Dismiss & remember – Ignore an extension you want to keep and we won’t nag you again (stored locally, never online).

Zero setup, zero data collection – Pure client‑side code; MV2 Checker never leaves your browser or phones home.
Why install today?

Beat the deadline – Manifest V2 shut‑off begins rollout June 2025. Don’t wait for Chrome to flip the kill‑switch.
Keep critical tools alive – Password managers, ad‑blockers, tab helpers—know which ones need replacing before they vanish.
Stay in control – IT admins and power users get a fast audit without digging through chrome://extensions.
Privacy first – No account, no analytics, no trackers. The scan runs entirely on your device.
Open source & tiny – Fewer than 100 lines of JavaScript. Inspect the code on GitHub and fork away.
