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/.

does what it's supposed to. Doesn't have Linux browser imitation. android works for Amazon mp3 downloads (for now)
htmlでは問題ないがJavascriptの偽装が出来なくなったね 他のでも一緒なのでこのアドオンが悪いわけじゃないけど、仕方ないので暫くはアドオン使わないで偽装することにした
don't work after last update
How do you use this - give an example. All the info seems for people that have the old version and are updating - with no info on how to implement this. Maybe I've done it right, but it doesn't work? You need to go to basics and put together a step-by-step HOW-TO. Also the Report a Prolem section does not work - don't know if this is a Chrome Store problem - there is no publish button!
Does not work for google chrome ( In Yandeks Browser was got :)
Doesn't work half the time.
This is an amazing tool, but was not working at all today, removed and re-added and now working fine again. Not being able to use my chromebook with ebay selling was incredibly annoying, this tool saved me from getting rid of my chromebook.
Where is custom option?
Used to have presets but the latest version got rid of them. No longer useful for watching Netflix in Xubuntu. [Update: reinstalled and presets are back but User-Agent causes Gmail to stall when loading]
When it works, it's awesome. Spoof iOS, resize the browser screen and there ya go! But it stopped working a few days ago. We use it for testing purposes (as I'm sure most do), and it's a VERY handy extension!!!
