Spoofs & Mimics User-Agent strings.
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.
NOTE: if Google sites / YouTube have problems after using a mobile user-agent, you may need to switch the user-agent back to Chrome *and* clear your cookies for the sites to treat the browser normally again.
