This video provides a detailed demonstration of how to find, modify, and switch User-Agent identifiers in the Chrome browser. It helps users easily simulate the experience of accessing websites on different devices, such as phones, iPads, and BlackBerries. The User-Agent is device information sent by the browser to the website, which determines whether the website displays different interfaces and functionalities based on the device type. The tutorial covers the entire process from conceptual explanation to practical operation: first, it explains what User-Agent is and how it works, then it gradually demonstrates how to temporarily switch device modes through Chrome Developer Tools (e.g., switching the computer browser to an iPad mobile view), and finally, it adds a quick query method for parsing User-Agent strings using online tools. The entire operation is simple and intuitive, allowing even users managing multiple accounts or performing batch tests to quickly master device environment switching techniques, effectively improving work efficiency and testing flexibility.
