Have you ever been restricted from using a website because you use Chrome? Do you want to test to see what your mobile site looks like on your desktop? All is possible with the User-Agent Switcher Extension.
Even in 2013, many website still require you to use Internet Explorer to access them. However, most of these websites will still function correctly in Chrome. So how do you get past these restrictions?

User-Agent Switcher Extension allows you to change Chrome’s user agent to a wide variety of different browsers, such as Internet Explorer 6 to 9, Firefox, Opera and Safari; including the operating system version. If you want to see what a mobile website looks like, you can switch the user-agent to Android, iPhone and Blackberry.
The extension will update its list of support user-agent, adding new browser versions. You also are given the option to add your own user-agent strings.
I use Chrome OS full time, and I have come across websites which block access because I am not running Windows or Mac OS X. To get around this issue, I created a user-agent option which will change my user-agent string to Google Chrome running on Windows 8.
