Extension Auditor - Security & Privacy Analyzer EN

Browser extensions, while immensely helpful, are also incredibly powerful. Their vast reach to millions of users makes them attractive targets for malicious actors.

Malicious code embedded in extensions can collect sensitive user data, inject unwanted ads, or misuse computing resources—all without the user’s knowledge or consent. This underscores the risk posed by seemingly trusted extensions that can “go rogue” or become compromised, jeopardizing your data and privacy.

Extension Auditor aims to raise awareness by providing visibility into all installed extensions that request high-risk permissions.

Although Microsoft's Security, Trust, and Safety teams work tirelessly to protect users, maintaining a safer browsing environment requires collaborative efforts.

By staying vigilant, actively monitoring permissions, and fostering cooperation among users and the developer community, we can collectively reduce the risks posed by malicious extensions and make browsing safer.
