Internet Explorer is least popular among the developers using Open technologies for web development. Most of the developers prefer Chrome and Firefox because of their developer-friendly features. Additionally, there are tons of browser extensions available for these browsers, which makes integrated development easier in the browser. Internet Explorer also has some awesome tools to develop and test web apps and sites, including option to change the default User-Agent string. Users can set their custom User-Agent strings or choose from the list of UA of popular browsers like Firefox, Chrome, Opera, Safari for iPad, IE for Windows Phone and older versions of Internet Explorer.
To change or spoof the User-Agent string in Internet Explorer, you don’t need any third-party tool or complex trick to use. This option is built-in in the IE similar to Opera and Google Chrome browsers. To change the UA string, launch the developer tools of IE by pressing the F12 key. It may take some seconds to open. Now, select the option “Change user agent string” in the Tools menu as shown in the screenshot below:
You can choose any available option from the menu which includes Firefox, Chrome, Opera, IE6 etc. To set a custom User-Agent string, select the option “Custom…” and enter the details. You can provide random user agent string in IE and test websites and apps. Moreover, you can also change the rendering mode of Internet Explorer and set it to the that of previous versions to ensure proper rendering for all visitors.
Apart from development purposes, changing UA string can be helpful in dealing with the browser discrimination.
