User-Agent Switcher is a simple, but very powerful add-on, and much easier to browse the Internet, regardless of which operating system or browser you prefer. It provides a toolbar button that one can use to toggle between different commonly used user-agent strings. In simple words, it’s the simplest way to switch between user-agents in your browser.

What’s a User Agent?

A user agent is a small text description of someone’s device which is sent with every web request.  Websites can detect the browser someone is using and serve different content – which is why iPhone and Android users see special mobile websites when they browse the web. With this browser extension, anyone can quickly and easily switch between user-agent strings.  Also, they can set up specific URLs that they want to spoof every time.  

Changing User-Agent allows one to mimic, spoof, or fake other browsers, or devices.

What does a browser User-Agent Switcher Do?

You might have noticed that Google displays the content differently on a windows phone and differently on an android phone. This is simply because of the user-agent. It changes the user agent of one’s browser. In simple words, it is a string made up of text which describes one’s operating system, browser, rendering engine, and other important details, which is used to change the way content is displayed. This extension gives you the power to modify this string which comprises text sent through HTTP headers so that you can make the web servers believe you are browsing from a different browser rather than one is actually using. Understand it like this, you are making the web servers believe that you are using an android phone instead of a windows phone which you are actually using.

Why would one want to use a browser User-Agent Switcher?

There are many reasons why one would want to use a browser user-agent switcher, some of them are:

Web Development:

Web developers developing a website want to see how it is looking, performing on different browsers. So instead of downloading several browsers which can be hectic, developers go for a user-agent switcher which lets them switch their browser’s user-agent and gives them a sneak peek at how their works look in other browsers.

Website on mobile:

Suppose a website has features that are available only to mobile phones, so instead of looking up the website on their phone, one can switch its browser user-agent to mobile phone or if a developer wants to see how its website look on a mobile phone, simply he will change the browser user-agent to mobile phone and see how it looks.

Browser restrictions:

There are some websites that restrict your access depending upon the browser you are using, it can be very hectic to install browsers every time there is a browser restriction. Instead, one can simply change its user-agent to a browser that isn’t restricted.
