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/.

使う時に拡張機能のオンオフして使っていたのですが、最近挙動が変化。 以前はオフにして再度オンにしても直前に選択していたUser-Agentが自動で選ばれていた。 今は一度オフにすると直前に利用していたのがリセットされるので、User-Agentを再度選択する必要がある。 地味に面倒なので戻して欲しい。クローム側の変更による不具合なら改善を希望。 追記。 Permanent Spoof ListでDomain部分にhttps://、User-Agent String部分は任意のものを設定。 これでオンオフにしただけで自分の使いたいものが自動で適用されました。
It is really doesn't work, it is still showing my real browser and real system： https://www.whatismybrowser.com/ YOUR WEB BROWSER LOOKS LIKE: Chrome 124 on Windows 10 But it's announcing that it is： Firefox 120 on Linux
我下载使用这插件之后进入一些网页。出现请取消阻止 challenges.cloudflare.com 后继续，删除这个插件也没有。有没有谁知道如何处理这种情况的朋友。
Версия 2.0 не работает в браузере Opera, предыдущая 1.1.0 нормально в Opera работала... Установил обновлённое расширение на Chromium - работает, но никаких отличий с прошлой версией нет, даже встроенные User-Agent не обновлены на актуальные версии. В чём смысл такого тупого обновления, чтобы пользователям Opera нагадить?
Misleading. The actual result from https://www.whatismybrowser.com/ is not as shown in the previews. WhatIsMyBrowser.com can easily see through the trickery.
Huh .. can select default for Chrome, but how about other platform .. I would agree useless.
不能自定义，且不支持 Microsoft Edge
yes it works thank you very much you save 3 hours of my life
一点都不好用！！！无语至极！！！
Useless. Does not contain a complete selection of user-agents, and does not permit you to input your own.
