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.
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!
