Product summary

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/.

Very handy! Have had this extension installed for years, perfect for testing purposes, and also provides a lot of random uses when you get creative with it! Thanks for the great extension!
muito bom, otimo simulador.
切换之后并没有效果，有些只能在chrome显示的效果切换到Firefox之后依然能够显示
Simply works. Please add white listing.
很喜欢，但很久没更新了，希望多提供一些新的 user_agent
求更新内置的User-Agent模板 太旧了
Ставил расширение только чтобы вернуть youtube старый дизайн. Не могу дать 5-звезд, потому что гугл все портит!
적용도안되고 개열받게하네
很奇怪,访问某些网站的时候明明没有设置规则却自动转换了UA,屡次调整都还是跳回来,神烦
Thanks. Love the "Permanent Spoof List" option where I can set domain specific user agent
