CookieScope

A powerful tool for debugging cookie issues, analyzing traffic and privacy, or learning about HTTP cookies, with a focus on simplicity, security, and user control. Designed for web developers, security researchers, and privacy enthusiasts to monitor and extract cookies in real-time over a sidebar.

Features: • Two modes: • Multi-Tab Capture, • Active Tab Only.

• Copy Options: • Individual cookies for one tab or the entire capture from all tabs. • Cookie JSON only or full tab content (title, cookies, JSON). • Buttons, CTRL+A, right-click, or mouse drag.

• Save Options: • For a single tab (e.g., cookies_x_com_2025-09-01T03-47-00.json). • For the entire capture for all open tabs (e.g., all_cookies_2025-09-01T03-47-00.json).

• Cookie Capture: • Newest cookie at the top. • Updates on tab activation, cookie changes, or page loads.

• Pause/Resume: • Pause updates to prevent refreshes during analysis. • Resume with queued updates.

• Privacy Support: • Displays a message and “Open Privacy Settings” button if no cookies are found, linking to Mozilla’s Enhanced Tracking Protection guide.

• Performance: • Uses a 2000ms debounce for updates (except tab activation) to balance responsiveness and resource usage.

Security and Privacy: • Minimal Permissions. • No Data Collection: Processes cookies locally without storage or transmission. • Safe DOM. • No Third-Party Libraries: Pure JavaScript, HTML, and CSS. • Error Handling: Provides user-friendly alerts for clipboard or download failures. • Manifest v2: Complies with Mozilla’s add-on standards.

• Limitations: • Firefox’s Enhanced Tracking Protection may block cookies; disable over Settings or the provided link. • Unsupported URLs: an error message displayed. • Clipboard access may fail in rare cases; use Ctrl+C as a fallback. • Multi-Tab mode may increase memory usage with many tabs.
