About this extension

🍪 NDT Cookies — Cookie Manager & Editor
View, search, copy, edit, export, import and back up website cookies in a lightweight interface.

📤 Export & Import
Support for Browser JSON, Netscape (.txt) and Puppeteer JSON. Export to files or copy to the clipboard; import from files or pasted text.

🔎 View & Find
Table, raw data and HTTP Header views. Inspect cookie attributes, search and filter cookies, view decoded values, and manage the current website or related subdomains with permission.

✏ Edit with Confidence
Edit values, expiration, session status, Secure, HttpOnly and SameSite. Stage changes, review before saving, discard drafts, detect external changes and verify saved cookies.

📥 Import Preview & Results
Preview and select cookies before importing. Identify invalid, expired, duplicate or unrelated records. Values are hidden by default, with progress, cancellation and a results summary.

💾 Backup & Clear
Download an optional backup before clearing cookies. Deletion requires confirmation. Protect exports, clipboard copies and backups with password encryption, and import them again with the password.

🌓 Comfortable Workflow
Popup and full-tab interfaces, light/dark themes, saved preferences, optional source-tab reload and 11 languages. Incognito/private browsing requires user-enabled extension access. Firefox supports container-aware cookie handling.

🔒 Local & Private
Cookie data is processed locally and is not sent to external servers. Website access requires the necessary permissions. No cloud sync or automatic backups. Browser and format limitations apply.

Developer comments

NDT Cookies processes cookie data locally in your browser. No account is required.

Usage notes:
• Grant website access when prompted to manage cookies for that site.
• Import Preview lets you review and select cookies before writing any changes.
• Editor changes remain staged until you review and confirm Save changes.
• Editing, replacing, or clearing cookies may sign you out or change website behavior. Export a backup first.
• Use Browser JSON when you need to preserve Firefox-specific cookie metadata. Netscape and Puppeteer formats do not preserve all attributes.
• On Firefox, imports target the cookie store/container of the source tab.
• Password-protected exports require the same password when importing.

When reporting a problem, include your Firefox version, the steps to reproduce it, and any displayed error message. Do not share cookie values, session tokens, passwords, or unredacted cookie exports.
