About this extension
User Agent Switcher is a powerful tool that allows users and developers to easily switch User-Agents to simulate web access from different devices, browsers, or search engine spiders. It supports high customization, enabling users to set User-Agents based on hostname, window, or random mode. It also modifies JavaScript properties like userAgent to ensure comprehensive simulation. For developers, it helps test website compatibility across devices and Bot blocking or spider crawling status. For regular users, it can protect privacy or access restricted websites. It works on multiple platforms, including Chrome, Firefox, Edge, and Opera, and is easy to use.
Updated to version 1.2, supporting custom UA and beautifying the interface. Welcome to continue to make requests!
