Understanding Users' Knowledge about the Privacy and Security of Browser Extensions
summary
Online survey with 353 participants measures attitudes, knowledge and preferences about browser-extension permissions and finds concrete gaps: users express interest in privacy yet do little to protect data, report limited technical knowledge about extensions’ capabilities, and favor permission text that builds a clear mental model. The paper quantifies those gaps, tests preference patterns for permission wording, and recommends clear language, technical controls, and distinct responsibilities for safer extension permissions.
