About User-Agent Switcher and Manager
User-Agent Switcher and Manager spoofs the identity your browser presents to websites. It changes the User-Agent sent in request headers and the matching JavaScript properties such as navigator.userAgent, navigator.appVersion and navigator.platform, so pages see a consistent picture.
It also handles newer identification methods, including Client Hints headers and the navigator.userAgentData object. Web developers use it to test how sites respond to other browsers and devices, and others use it to get past sites that refuse a particular browser.
Strengths
- Changes both request headers and JavaScript navigator properties
- Supports Client Hints and navigator.userAgentData
- Global or per-site rules
Limitations
- Spoofing can break sites that rely on accurate browser detection
- Does not hide other fingerprinting signals
