Lets you easily switch between different user-agents in your browser, giving you more control over how your online identity is represented and allowing you to test website compatibility with various browsers. This extension is particularly useful for developers, testers, and anyone who needs to simulate different browsing environments. Simplest way to switch between user-agents in your browser!

Overview

User Agent Switcher is simple, but powerful extension. And much easier to use the Internet, regardless of which browser or operating system you prefer.
It adds a toolbar button that you can use to toggle between different commonly used user agent strings.

So what’s a User Agent?

A user agent is a small text description of your device that is sent with every web request. Websites can detect the browser you’re using and serve different content - this is why iPhone and Android users see special mobile websites when they browse the web.

With this chrome extension, you can quickly and easily switch between user-agent strings. Also, you can set up specific URLs that you want to spoof every time.

Changing User-Agent allows you to mimic, spoof or fake other browsers, devices or search engine spiders.

Note:
Sometimes problems may occur after using a mobile user-agent, and won't switch back no matter what you spoof, you will need to switch the user-agent back to Chrome and clear your cookies for the sites to treat the browser normally again!
