About User-Agent Switcher: Device Identity Simulator

Summary: Simulate different device fingerprints (User-Agent, Screen, Canvas) for testing and debugging purposes. Description: Device Identity Simulator allows developers and QA engineers to easily simulate various device identities directly from their browser. Test how your website responds to different devices without needing physical hardware. Key Features: 🖥️ Device Simulation: Switch between 11 preset devices including Desktop, Laptop, Mobile, and Tablet. 📱 Advanced Fingerprint Spoofing: Automatically modifies User-Agent, Client Hints (Sec-Ch-Ua), Screen Resolution, Canvas, and WebGL fingerprints. 🔒 Full Client Hints Support: Correctly spoofs Sec-Ch-Ua, Sec-Ch-Ua-Platform, and Sec-Ch-Ua-Mobile to bypass modern fingerprinting. 🧹 Auto-Clean: Automatically clears Cookies and Storage when switching devices to ensure a clean testing environment. 🔄 Auto-Refresh: Automatically reloads the page to apply new device settings immediately. 🌍 Multi-language Support: Available in English, Chinese, Spanish, German, and French. Privacy Policy: This extension operates entirely locally. No user data is collected or sent to external servers.
