The Clir DLP Extension requires :///* permission to track and analyze file uploads across various websites to prevent data leakage. Since users may upload files to multiple platforms (e.g., cloud storage, email, collaboration tools), restricting permissions would create security gaps. The extension only captures file metadata (not contents) and enforces corporate security policies without altering user browsing. Using activeTab or domain-specific permissions is insufficient, as uploads can occur passively. This broad permission is essential for real-time DLP enforcement while ensuring compliance with privacy regulations.
