Prior work - which used data collected in the United States between 20 - found that MTurk responses regarding security and privacy were generally representative for people under 50 or with some college education.
Security and privacy researchers often rely on data collected through online crowdsourcing platforms such as Amazon Mechanical Turk (MTurk) and Prolific.
Based on our findings we derive recommendations for the improvement of browser extension permission dialogues through clear language, technical improvements and distinct responsibilities. They have limited knowledge about the technical abilities of browser extensions and prefer permission statements that evoke a clear mental model. We found that users report interest in seeking information, trust the developers but do little to protect their data. To understand users' awareness of these privileges and the associated threats, we conducted an online survey with 353 participants, focus-ing on users' attitude, knowledge, and preference towards extensions' permission requests. These permissions, however, give very limited information about the fact that they allow the extension to access user's personal data and browsing behaviour, posing security and privacy risks. To perform these functions, users must grant certain permissions during the installation process. Browser extensions enrich users' browsing experience, e.g., by blocking unwanted advertisements on websites.
