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.

Worked great the last time I used it. Apparently Chrome changed something [purposely?] to break this extension. I hope the developers eventually pop-in and maybe fix it for those of us that need an extension like this..
Was a great Extension till it stopped working, Now hwen I press the menu button to change settings it only shows a white box with no letters or options. it is completely broken and unfunctional.
didn't work for me at all. couldn't enter custom user-agent string, at least what i entered never showed up in any list ... json was created and i exported that into a file and then imported it: still nada. whatismybrowser showed no change from default ... installed on chrome 109 ...
user-agent Append 기능이 정상작동하지 않고 Replace됨. 그동안 유용하게 썼었는데 다른걸 써야겠네요.
Al inicio, funcionaba perfectamente. Ahora, por algun motivo, hay un error donde la lista de Agentes de Usuario desapareció, y no hay manera de restaurarla, ni siquiera añadiendolas manualmente Si bien, la recomendaba al principio, el estado actual de la extension es INUTILIZABLE. Una pena
6月5日以降使用できなくなりました
ça fait long temps ,ne fonctionne plus.
As of Chrome 125.0.6422 and Edge 125.0.2535 - this extension is broken, unfortunately.
I develop web-based data management solutions, and I use the user agent as my debugging "back door", appending a a keyword to the end of the default user-agent that my code knows to look for. This extension makes that easy. Have to edit and downgrade. This has been my go-to switcher, but since the last update (more than a year ago!) the permanent spoof list cannot be overridden, even if the persist-no-matter-what option is not checked. I've spent enough time trying to track down bugs caused by this that it's just not worth keeping this one. It appears the extension is abandoned. Shame.
