About this extension
USER AGENT SWITCH is a powerful browser extension that allows you to easily simulate user agent information from various devices and platforms. Based on the million-level user agent database provided by useragents.io, this extension offers a convenient browser identity simulation solution for developers, testers, and regular users.

Unlike other user agent switchers, it allows you to set your frequently used U/As in the side panel. You can also open the useragent.io website, where you can choose from millions of U/As. They are scientifically categorized so you can quickly find the U/A you need.

☑️ Core Features
1️⃣ Massive user agent library: Based on the million-level user agent database from useragents.io
2️⃣ Simple setup: Intuitive interface with no complicated configurations required
3️⃣ Multi-device simulation: Supports simulating various browsers, operating systems, mobile devices, and desktop platforms
4️⃣ Quick filtering: Convenient filtering function to help you quickly find the desired user agent

☑️ Usage Instructions
1️⃣ Click the extension icon in the browser toolbar to open the user agent list page
2️⃣ Use the filtering function to find the user agent you need
3️⃣ Move your mouse over the target user agent and click the "Switch to this U/A" button
4️⃣ Open a new page or refresh the current page for the settings to take effect

☑️ Application Scenarios
🟠 Website compatibility testing: Check how websites display on different browsers and devices
🟠 Developer debugging: Simulate different environments for front-end development and debugging
🟠 Bypassing restrictions: Get around some website access restrictions based on user agents
🟠 Privacy protection: Enhance browsing privacy by changing user agents

⚠️ Notes
Some websites may detect browser environments through other methods, so changing the user agent alone may not fully simulate the target device
After switching user agents, you need to open a new page or refresh existing pages for the changes to take effect
It is recommended to switch back to the default user agent after testing to ensure a normal browsing experience
