What Is Cookie-Editor?
Cookie-Editor is a browser extension (add-on) that lets you create, edit, and delete cookies for the current tab, and import or export them. It's aimed at people who need to inspect or change cookies directly rather than through a browser's built-in developer tools — for example, developers testing a page, QA engineers checking site behavior, SEO specialists, or anyone who wants to manage cookies manually for privacy. It runs on Chrome, Firefox, Safari, Edge, Opera, and other Chromium-based browsers, plus Firefox for Android and Safari for iOS with a touch-optimized interface.
What Cookie-Editor does
The extension is built around a short list of cookie operations, all scoped to the page you're currently viewing:
- View a list of all cookies on the current page
- Create a new cookie
- Edit an existing cookie
- Delete one cookie or all cookies
- Export and import cookies, including exporting directly to your clipboard
According to the project, these actions are designed to take "a maximum of three clicks," and the extension is positioned as a productivity tool rather than a full developer console replacement.
Where you can use it
Cookie-Editor is available across most major browsers and on mobile:
| Platform | Availability |
|---|---|
| Desktop | Google Chrome, Firefox, Safari, Edge, Opera, and other Chromium-based browsers (e.g., Vivaldi) |
| Mobile | Firefox for Android, Safari for iOS (touch-optimized interface) |
The extension can be accessed from your toolbar, from your browser's DevTools, or from your phone, depending on the platform.
Who it's for
The project lists several intended uses:
- Development — optimize time when working on a web page
- Software quality assurance — test a website's behavior
- SEO — inspect and manage cookies relevant to crawling or session behavior
- Manual cookie management — handle cookies yourself for privacy reasons
If your task is simply to see what cookies a site has set, or to add, change, or remove one without writing code, Cookie-Editor is designed for exactly that.
Practical notes
- Open source and privacy-focused. The source code is on GitHub under
moustachauve/cookie-editor, and the project states that "your privacy is important." You can review or contribute to the code. - Suggestions and bugs go through the GitHub issue tracker, which the developer says will be addressed as quickly as possible.
- Developer: Christophe Gagnier (Moustachauve). The project is supported by DigitalOcean and offers a GitHub Sponsor option.
If you want to try it, install it from your browser's extension store for the platform you use, then open the extension on any tab to see and manage that page's cookies.
