Summary

Hide ▲

A browser-security analysis found more than 80 browser extensions explicitly reserve the right to sell user data, exposing users to disclosed but widely overlooked privacy monetization. The cohort spans streaming, ad blocking, and productivity tools with millions of installations, including 29 business-focused extensions that gather enterprise browsing data. The finding matters because broad privacy-policy language can let extensions monetize browsing behavior at scale without obvious warning signs for consumers or administrators. The same analysis also found 71% of Chrome Web Store extensions do not publish a privacy policy, widening the visibility gap.
