Chrome users – get an alert when extensions are in danger of falling into wrong hands

A new Chrome add-on, Under New Management, by developer Matt Frisbie, alerts users when their extensions change ownership to combat extension subversion—where popular add-ons are acquired and quietly updated to harvest data, inject ads, or perform other monetizable abuses. The article explains current Google defenses (automated scanning, Manifest v3), the challenges around opaque ownership transfers, and notes that Chrome’s team is considering WebExtensions API changes inspired by this work, while Frisbie’s ExBoost service currently powers the ownership checks.
