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/.

Every time I install this add-on, I constantly get random malware type popups. This gets very annoying.
Wonderful tool. We have applications designed to run on the iOS operating system. This tool allows me to test and use the app on my windows workstation. Use it all day long and it works great. I did have an issue and needed to re-download once. Then it worked fine again.
When I downloaded this to get the full version of outlook web app, it made my internet stop working - making my chromebook useless until I deleted it. DO NOT DOWNLOAD!
Nice extension, but it doesn't work. At least on Linux, Chrome Version 40.0.2214.111 (64-bit) Sorry, I managed to make it work. For everybody needing this info: you need to go to extensions settings and check the box "Allow access to file URLs" fot this extension. Then it works :) Thank you for this great plugin!
添加了自己手机的UA，爽~
I'm using the extension to make OWA show the "enhanced" view. The user-agent isn't getting spoofed when I reload the browser if the tab is pinned. BTW, it also uses --auth-server-whitelist for kerberos. To fix, I have to clear the sites cookies, then reload the page. :(
Great extension
