Neeno's Cookie Importer

The definitive session management suite for developers to master browser cookies with precision, speed, and unlimited scale.

Neeno's Cookie Importer transforms the complex workflow of managing session data into a seamless experience. Powered by a brand new IndexedDB architecture, v2.4.8 evolves into a heavyweight toolkit: allowing you to Snapshot unlimited sessions for later use, Lock critical cookies against accidental deletion, and Edit advanced attributes directly from a non-blocking UI.

Whether you are debugging intricate authentication flows, migrating user sessions between profiles, or configuring test environments, this extension provides a robust interface to handle Netscape, JSON, Puppeteer, and Python formats without the hassle.

🚀 Unlimited Session Snapshots & Inspector

Never lose a session state again, and never worry about storage quotas.

• IndexedDB Power: Save practically unlimited session profiles. Our new lazy-loading architecture ensures the UI remains lightning-fast, fetching heavy cookie data only when you interact with a snapshot.
• Create & Restore on Demand: Instantly back up your current browser cookies into a named snapshot, or swap between saved accounts effortlessly.
• Inspect Before Restore: View the contents of any snapshot without applying it. The detailed view groups cookies by domain, letting you verify the session contains the correct data.
• Memory-Safe Exports: Export your entire snapshot library to the clipboard. The new streaming cursor prevents memory spikes even when handling massive datasets.

• The "Danger Zone" Deep Clean: Gain granular control over your browser's data. Selectively wipe IndexedDB, Local/Session Storage, Service Workers, Cache, and Form Data all from one compact grid—while keeping your locked cookies perfectly intact.
• Advanced Visual Filters: Toggle, filter, and modify Secure, HttpOnly, and SameSite flags instantly using the new compact filter pills in both the Manage and Import modals.
• Cookie Locking: Mark specific cookies as "Locked." These protected cookies will persist even when you hit clear, ensuring you stay logged in to essential tools while wiping the rest of your session.
• Revive Expired Cookies: A dedicated tool automatically detects expired cookies in your clipboard and allows you to renew their expiration dates with preset or custom durations, saving your preferences for future sessions.

Turn your browser cookies into code instantly. The Export Suite allows you to convert your active cookies into any format you need for development:

• JSON & Netscape: Standard formats for archiving or using with wget and curl.
• Python & Puppeteer: Generate ready-to-paste code dictionaries for your automation scripts, now featuring upgraded parsing that flawlessly handles falsy values and escaped single quotes.
• Header String: Get a raw name=value; string for quick API testing.
• CSV: Export cookie data to a spreadsheet file or clipboard for auditing and documentation.

Keep your hands on the keyboard with our expanded shortcut integration:

• Alt+Q: Instantly clear all unprotected cookies.
• Ctrl+S: Quick save your current session into a snapshot.
• Ctrl+R: Instantly restore your most recent snapshot.
• Expanded Shortcuts Menu: Click the list icon in the footer to access a complete guide to all keyboard bindings.
• Configurable Logging: Keep your built-in Activity Log clean by setting custom limits on the maximum number of debug entries.

• Smart Store Support: Fully compatible with Incognito mode and Firefox Containers, ensuring cookies are applied to the correct isolated storage ID.
• Smart Domain Matching: Intelligent logic automatically resolves "www" vs non-www conflicts, ensuring cookies are applied correctly even if the domain structure varies.
• Conflict Resolution: Choose exactly how to handle duplicate cookies during import—Overwrite, Skip, or Rename—to prevent accidental data loss.
• Security Compliance: Built-in logic automatically enforces browser security standards by validating __Host- and __Secure- prefixes.
• Theme Adaptive: A polished, modern interface that syncs perfectly with your system’s Light or Dark mode.
