Several elevated signals. Read the findings before sharing this with your team.

Abandonedsafety score reduced by 40 points

  • No update in over 6 years
  • The developer's website is no longer reachable
  • Built on Manifest V2, which Chrome and Edge are retiring
Why this matters

An unmaintained extension keeps whatever flaws it shipped with, and a listing with users but no owner is an attractive target to buy and repurpose.

Automated analysis of publicly available code — not a professional security audit. It may produce false positives and does not prove an extension is unsafe or safe. Treat it as one signal among many. Disclaimer · Report an issue
