Fbmfox is a verifiable SaaS tool (Chrome Extension) for Facebook Marketplace dropshipping, primarily active around 2021-2022. However, the project shows significant red flags: the extension has been flagged for malware and delisted from the Chrome Web Store, user reviews cite 404 errors and billing fraud, and the submission itself contains blatantly false claims (e.g., 'most people have used my product', 'everyone' audience). While it historically had ~5,000 users, its current utility is severely compromised, and the submission quality is critically low.
