Overview
Custom UserAgent String is a user-friendly add-on, which helps in adding a customer UserAgent string for a desired website or URL.
A useragent is a string of text that the web browser sends to a web server to identify itself and its capabilities. This information is used by the server to determine how to handle the request and to provide the appropriate response(s). In JavaScript, the "navigator.userAgent" property is used to access the useragent string on the client side. The useragent string typically contains information about the browser version, operating system, and physical device. For example, a useragent string might look something like this: "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/84.0.4147.135 Safari/537.36". This useragent string indicates that the browser is Mozilla version 5.0, running on Windows 10, and using the AppleWebKit rendering engine. It also shows that the browser is Chrome (version 84.0.4147.135). Once the useragent string has been obtained, as an example, you might want to use a different set of CSS styles or JavaScript functions for vsrious browsers to ensure that your website looks and behaves consistently across different platforms.
A useragent string typically includes several different segments of information about the user's browser or device. These segments can include, The browser name and version: This segment of the useragent string typically includes the name of the user's browser, such as "Chrome" or "Firefox," as well as the version number of the browser. This information is used by the server to determine which version of the website to serve to the user. The operating system: This segment of the useragent string typically includes the name and version of the user's operating system, such as "Windows 10" or "iOS 13." This information is used by the server to tailor the website to the user's specific operating system, such as serving up a mobile-optimized version of the website for users on a smartphone or tablet. Additional features or capabilities: Some useragent strings may include additional information about the user's browser or device, such as whether it supports specific technologies, such as HTML5 or CSS3, or whether it has certain hardware capabilities, such as a touch screen or high-resolution display. This information is used by the server to enhance the user's experience on the website. Unique identifiers: Some useragent strings may include unique identifiers, such as a device or browser fingerprint, that are used to identify the specific device or browser that is accessing the website. This information can be used for security purposes, as it allows the server to block or redirect traffic from known malicious bots.

Frequently Asked Questions
1. What is Custom UserAgent String?
Custom UserAgent String (abbreviated as CUAS) is a browser addon (extension) that enables you to quickly change the useragent (UA) of your browser to your desired value. There is also an ON/OFF switch to turn the extension ON or OFF from the browser toolbar. Once you install the addon, please go to the options page to start working with this extension. At the top section there is a table with more than 100 useragents which you can choose and add to the UA table. Each UA can then be modified to match your need.
2. How does a useragent string looks like?
Most Web browsers use a User-Agent value as follows: Mozilla/[version] ([system and browser information]) [platform] ([platform details]) [extensions]. For example, Safari on the iPad has used the following: Mozilla/5.0 (iPad; U; CPU OS 3_2_1 like Mac OS X; en-us) AppleWebKit/531.21.10 (KHTML, like Gecko) Mobile/7B405.. The specific format of a useragent string can vary depending on the browser and the platform it is running on, so it is not always possible to determine exactly what each piece of information in a useragent string represents. However, most useragent strings include similar information and can be parsed by servers and other software to determine the type of browser that is accessing a website.
