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/.

Version 1.1.0 no longer works effectively. (supposedly removed the functionality of Javascript Objects spoofing) Last working version was: 1.0.43, which can be downloaded here: https://www.crx4chrome.com/crx/169490/ FYI, UA Detection Test: HTTP Header Based: https://www.whatismybrowser.com/detect/what-is-my-user-agent Javascript Based: https://webbrowsertools.com/useragent/?verbose=true While I haven't found an extension that can pass the Javascript Based one yet... (currently this extension works best for me) Friendly Reminder: The "Domain" field in "Permanent Spoof List" expects a RegEx so... mind your grammar. Suggestion and Feedback: The "Import/Export Settings" is apparently broken, so apparent that I don't even need to say where & how... (one thing: "Permanent Spoof List", the rest... try you'll see) Cannot seem to find a way to adjust the order of the entries in "Permanent Spoof List" (...deleting everything then rewrite doesn't count), while the order does matter... (top of the list has higher priority) Not working on "file://" URLs?.. (even if explicitly allowed of doing so) On the Javascript Objects spoofing, the navigator object in <iframe>s doesn't seem to be manipulated. (forgotten?..)
После переустановки перестало работать. Применяю любой профиль через меню расширения, затем смотрю в консоли разработчика значение navigator.userAgent - ничего не меняется. При этом через саму консоль смена UA работает (Network Conditions -> User Agent _> ...), но это приходится делать вручную каждый раз для открытой вкладки, да еще все кукисы для станицы удалять.
window.navigator.userAgent 没有改
Da circa un mese non funziona più con Instagram. Ha perso gran parte della sua utilità.
Funzionava bene, adesso e' gia' da un mese tipo che non funziona piu', qualcuno sa' consigliarmi una buona alternativa?
真是糟透了，根本没法用
Noice, Works perfectly!
まったく使えない、iphoneやandroidに設定してもずっとPC画面のまま。
Перестало работать
Me gusto muy útil pero seria mejor que también pongan XBOX
