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.

indispensable for developing mobile sites. don't know how I coped before!
Use this all the time. Tried many alternatives, and this one won me over on the first use. Continues to improve, also. Thanks Glenn!
Easy to use and is extensible. No longer need to keep some random .txt of my user agents. This plugin keeps them all for me.
Very helpful. Congratulations on the initiative!
Thanks Bro!!
Finnaly the Extension works and we have a Extension for User Agent Switching in Chrome. Great work! Now I need to find a list of User Agents for different Android devices.
I can finally ditch IEtab extension! Finally those MS fanboi servers that reject non-IE users can stop slowing down my PC. I now use Chrome for websites that have no idea that Chrome works just fine with them (even a few work ones!). Quick question: * Does this support Google sync for extension data? That is, are "Permanent Spoof" settings sync'd to other instances of the extension under the same Google profile? Suggestions: * Not immediately obvious how to revert back to 'normal' mode (chrome/default) * Redundant submenus - they're like "Success!" dialogs. If there's only one user agent option for a browser type (e.g. Chrome/Default), then trigger the selection when I click "Chrome". Don't make me click "default", as if I have some kind of other selection choices. Reminders: 1. This extension only changes a single string that a browser responds with when a server asks for it. It doesn't make Chrome actually emulate any of the long list of alternative (or very broken) browser versions that you can choose from. 2. Always clear your cookies for a given website if you start seeing weird behaviour, since some sites get confused when you use different browsers from the same PC.
Excellent! Got through YouTube's idiotic refusal to allow YouTube Remote to be controlled on a laptop!
great work
