Features & Capabilities

The Random User-Agent (Switcher) Chrome extension helps protect your online privacy by automatically changing your browser's user agent at set intervals. This user agent string acts like a browser fingerprint, revealing your device and software details to websites. By randomizing or manually setting user agents, this extension makes it appear as if you're browsing from different devices, safeguarding you from targeted tracking and JavaScript fingerprinting techniques.

Featuring lightweight operation and customizable options, users can select which browsers and operating systems to emulate, and create an exceptions list for specific sites. This extension is completely free, ad-free, and open source, providing a simple yet powerful tool to enhance your anonymity and security while surfing the web.
