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/.

Broken on Chrome 34 :(
Its nice. But sometimes it not work for Mac. Its annoying when it refuses to change the user agent and then I need to change it from Console
I removed it and readded it and it works again.
It's great except for when it decides at random to forget my custom user agents.
If unusable, remove and reinstall the app. Works fine after that !
The permanent spoof is not working. Fix this please!
Does what it is supposed to. I have been using it for a long time. Had some issues recently (see other comments, others had similar issues), but removing the extension and re-adding it fixed it.
Nice but now has a problem with my chrome (worked for a long time before this)
急に切り替えができなくなりましたが、再インストールでまた使えるように。
It works, if for example you choose IE9, if it's working a little IE9 icon will appear under the little mask. If it doesn't it's not working, in which case simply remove it from Chrome then re-add it. Regards, Mike
