Cookie & UA Manager

Save and restore Cookies and User Agent

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.
