User Agent (UA) is an important component that helps browsers recognize and interact with websites effectively. Understanding what User Agent is and how to change it can not only protect your privacy but also optimize your browsing experience according to your personal needs. In this article,Antidetect Browser Hidemium will explain in detail about User Agent, its role and guide you how to change User Agent on four of the most popular browsers today: Chrome, Firefox, Edge and Safari.
1. What is User Agent?
User Agent (abbreviated as UA) is an integral part of the HTTP protocol. It is a text string sent by a browser or application to a web server when a user visits a website. Through UA, the server can determine information such as the type of device, operating system, and browser the user is using.
When you visit a website, your browser automatically sends a User Agent string in the HTTP header. Each browser and operating system has a unique UA string. For example, the UA string might be “Mozilla Firefox on Windows” or “Opera on iPad.”
Websites will use information from the User Agent to display compatible content or restrict access based on the type of device or browser. Therefore, changing the User Agent properly will help you avoid some unnecessary access barriers or content restrictions.

2. Example of User Agent string:
Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/60.0.3112.113 Safari/537.36
Analyze the UA string above:
Mozilla/5.0: String opening, which is the usual default
Windows NT 10.0; Win64; x64: Operating system and system architecture information
AppleWebKit/537.36 (KHTML, like Gecko): Web engine for displaying content
Chrome/60.0.3112.113: Specific browser name and version
Safari/537.36: Secondary browser or platform compatibility information
Understanding the concept and how User Agent works will help you manage your web access activities more effectively. In the following sections, Hidemium will guide you in detail on how to change User Agent on the 4 most popular browsers today: Chrome, Firefox, Safari and Microsoft Edge - helping you improve accessibility and security when surfing the web.
3. The role of User Agent in web browser
User Agent (UA) is a string of information that the browser sends to the web server, which helps identify the type of device and software the user is using. The role of User Agent is important in ensuring website performance and compatibility:
Identifying the appropriate content format: Through UA, the web server can recognize the browser version and capabilities, thereby providing the most appropriate content for the user's device.
Increased compatibility: UA allows the server to adjust the display to optimize for each type of browser and operating system.
Support efficient resource distribution: Based on information from UA, the server can provide appropriate resources, contributing to improving page load speed and user experience.
Testing and Quality Assurance: Developers use UA to test compatibility and tweak websites across different browsers.
Collect analytics data: UA provides data that helps statistical tools track user behavior, thereby supporting content improvement and SEO strategy.
4. Benefits of changing User Agent
Changing the User Agent is a useful technique, especially for those who do web development, interface testing, or need to access restricted content. Here are some of the notable benefits:
Support for multi-browser testing: Changing UA helps developers easily simulate and test website interfaces on different browsers without having to install each software.
Simulate mobile experience: Users can preview the website interface on their phone or tablet just by changing the UA, which is very convenient in the process of designing responsive web standards.
Bypass browser access restrictions: Some websites restrict access if they detect an incompatible browser. Changing the UA will allow you to "emulate" a supported browser, making it easier to access content.
