Ever needed to quickly switch between user-agent strings on the fly? Developing a site that needs to work on both mobile browsers and desktop browsers? Sick of some archaic site blocking you because you're not using Netscape 4?
The User-Agent Switcher for Chrome is the answer. With this 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.
Please note that this does not provide improved privacy while browsing the Internet and that some sites might have other means to figure out that the browser is not what it pretends to be. Running this extension can have performance impact on your browsing experience due to its need to intercept and modify the data communicated to the server.
NOTE: if some sites have problems 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.
By installing this item, you agree to the Google Terms of Service and Privacy Policy at https://www.google.com/intl/en/policies/.

works ok until i try to use youtube
Using this for tmobile hotspot bypass. Problem is that youtube doesn't seem to work.
Perfect

It's great, but it doesn't play well with diqus commenting platform. Even when deactivated, it will stop disqus from working. It drove me crazy while I was trying to install disqus in my webpage.
The developers of this app need to leave browser properties alone. This extension overrides navigator.appName, and causes a ReferenceError saying "stopUsingAppNameForBrowserSniffingItsBad." This breaks any site that relies on that property, including any site built on jQuery Mobile. Had to disable this extension to continue development on our mobile site.
While this plugin was very useful, something broke today 1/10/2013. All embedded YouTube videos stopped working with the plugin installed, and also thumbnails on YouTube went missing. Disabling the plugin fixed the issue.
This extension worked great, until today. Because it started messing up YouTube. When I visit YouTube it wouldn't load certain scripts and images. The user-agent was set to Chrome > Default. After disabling the plugin the YouTube issues were gone.
"I like the extension, but from the last update it fails on a lot of sites with the javascript message: ReferenceError: stopUsingAppNameForBrowserSniffingItsBad is not defined If I disable the plugin the sites work." As Rody said, Same problem here.
Love this extension but the latest update has broken it for the one site I really need it for. Please fix ASAP then it will be 5*
