Cookie & UA Manager

About

Take control of your browser environment for testing and debugging.

Session Manager is a professional tool designed for developers, QA testers, and power users. It allows you to seamlessly manage, migrate, and clone web sessions across different browser environments with precision.

Key Features:

- Session Portability: Effortlessly export your active session—including cookies (from the current site or all related third-party frames) and your current User Agent—into a standardized JSON file.

- Precise Restoration: Import configurations with an intelligent engine that resolves domain scope issues and prevents duplicates during the restoration process.

- User Agent Emulation: Simulate different devices and browsers. The extension updates request headers and leverages the modern navigator.userAgentData API (Client Hints) to ensure accurate environment simulation.

- Conflict-Free Import: Automatically detects and clears conflicting cookies before restoring a session to ensure a clean testing state.

- One-Click Environment Reset: Instantly clear cookies from the active container and revert to the default User Agent, allowing for rapid re-testing without manually clearing the entire browser cache.

- Privacy Focused: All data processing occurs locally on your machine. No data is sent to external servers.

How it works:

1) Save: Choose whether to export cookies from the current specific domain or include all third-party resources active in the tab, then download your structured JSON configuration.

2) Restore: Upload your JSON file and click "Restore". The extension automatically wipes conflicting data, applies the new identity parameters (User Agent & Cookies), and reloads the page to activate the session.

3) Reset: Click "Reset to Default" to instantly clear all cookies from the container and revert to your genuine browser profile.

Technical Information & Permissions Usage:

To provide these features, the extension requires the following permissions:

- Cookies: Required to export session data to JSON and restore it from files.

- Scripting: Necessary to inject the navigator emulation scripts into the page context for accurate device testing.

- DeclarativeNetRequest: Used to modify the User-Agent HTTP header at the network level.

- Host Permissions: Required to access and manage cookies across different domains during the export/import process.
