- Ad-blocking extensions sometimes sell user data to advertisers, contradicting their purpose.
- A study found 82 extensions with policies allowing data sale, with 75 still on Chrome Web Store.
- Many extensions hide data-sharing terms in vague language or lack privacy policies entirely.
- Examples include ad-blockers like Stands AdBlocker and streaming-related extensions linked to a single network.
- Collected data includes browsing history, interests, and streaming habits, often sold for analytics or marketing.
- This data can lead to real-world harms like price discrimination or targeted scams.
- Users should check privacy policies, developer credibility, and reviews before installing extensions.
