The sudden disappearance of EditThisCookie from the Chrome Web Store in late 2024 left millions of developers without their trusted cookie management tool. The browser extension, which relied on the outdated Manifest V2 standard, was removed for failing to transition to Manifest V3—a modern security requirement that restricts extension capabilities. In response, a developer known as S-Hub created CookieJar, a next-generation cookie editor designed from the ground up to meet these new standards while introducing features that EditThisCookie never offered.
Unlike its predecessor, CookieJar does not merely display a flat list of cookies. Instead, it automatically organizes each cookie into six distinct categories, making it easier for users to understand the purpose and risk level of each one. This classification system leverages multiple detection methods, including pattern matching on cookie names, domain verification against known tracking lists, and analysis of cookie attributes such as HttpOnly and SameSite settings.
Built-In Privacy Insights and Profile Management
CookieJar introduces a privacy scoring system that assigns each website a 0-to-100 rating based on multiple factors. The score considers the number and types of tracking cookies detected, the presence of third-party cookies, and the security attributes of those cookies. A circular gauge in the extension’s popup provides an immediate visual summary, allowing developers to quickly assess whether a site’s cookie practices align with privacy expectations. For example, a site with dozens of advertising cookies and no Secure or HttpOnly flags would receive a low score, signaling potential privacy concerns.
Another standout feature is profile management, which enables users to save and restore sets of cookies for different scenarios. Whether testing authentication flows, switching between development environments, or debugging OAuth integrations, profiles eliminate the need to manually reconfigure cookies each time. A developer working on a multi-role application can save separate profiles for admin and user accounts, then switch between them with a single click.
Flexible Export Options and Cross-Browser Compatibility
CookieJar supports five export formats to accommodate various workflows:
- JSON for programmatic processing or integration with automation tools
- Netscape/curl format for use in command-line requests
- HTTP header format for direct API testing or debugging
- Puppeteer format for web scraping and automation scripts
- CookieJar format for importing into another instance of the extension
This versatility ensures that developers can seamlessly move cookie data between tools, whether they are debugging a backend service, running automated tests, or analyzing user behavior on a staging site.
Technical Foundations and Performance Optimizations
Under the hood, CookieJar adheres to Chrome’s Manifest V3 requirements by requesting only the necessary permissions: cookies for reading and modifying cookie data, and storage for saving user preferences. Host permissions are set to <all_urls> to allow the extension to interact with any domain, though access is gated by user interaction to maintain security.
Real-time updates are powered by Chrome’s chrome.cookies.onChanged event, which triggers whenever a site modifies or deletes a cookie. This eliminates the need for polling and ensures that the extension’s interface reflects the most current state of cookie activity. To handle sites with large numbers of cookies efficiently, CookieJar employs virtual scrolling for the cookie list, debounced search filtering to reduce unnecessary renders, and lazy classification that only processes cookies when they first appear in the viewport.
Global Reach and Commitment to User Privacy
Recognizing that developers and users span the globe, CookieJar ships with full localization in eight languages: English, Japanese, Chinese (Simplified), Korean, Spanish, French, German, and Portuguese. The extension uses a modular localization system, ensuring that all UI text can be updated without modifying the core codebase.
Perhaps most importantly, CookieJar itself collects no user data. There are no analytics, no tracking pixels, and no server-side logging. All cookie information remains entirely within the user’s browser, reinforcing the extension’s core value proposition: a tool that helps manage privacy without compromising it.
How to Get Started
CookieJar is available as a free extension on the Chrome Web Store, with optional pro features such as advanced profile management, bulk operations, and additional export formats available for a $4.99 monthly subscription. The extension is developed by S-Hub, a creator of developer-focused tools known for high-performance Chrome extensions tailored to productivity and workflow efficiency.
For developers who rely on cookie management for testing, debugging, or privacy audits, CookieJar represents more than just a replacement for EditThisCookie. It is a forward-looking solution that aligns with modern browser security standards while introducing new capabilities designed to make cookie management both intuitive and insightful.
