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.

OSを偽装したいが、chromeを選択すると素のuser-agentになってしまう。 Windows10用のuser-agent文字列を設定したが、java scriptのuser-agentを偽装できないので、正直なところ使いものにならない。
i'm only using this for my chromebook because of roblox's stupid update on the website making it impossible to use because they dont accomodate for fixing chromebook bugs despite letting it run on it. switching it to Opera makes it work fine, just how i need it to. However, there is an issue, even when i go back to "default" or turn the addon off. It messes up websites with touchscreen, for example, I like to draw on Aggie.io, which is a website you can draw on and draw with other people. This addon breaks touch screen, making it so i cannot zoom in or draw. I have to completely uninstall just so i can use most websites again. So, I will be using this for roblox, but i will have to uninstall and reinstall it a lot for some reason. Oh well. at least it works for the one thing i needed it to work for
It Works
i just use this for YouTube because windows phones get no ads. this works pretty good but the only use case i use it for is blocking youtube ads
One of the most limited and not-user-friendly extensions out there for UA switching, would not recommend
Doesn't provide even remotely recent UA strings, doesn't let you add them without downloading the XML directly from third party sites.
да я смотрю TV и управляю с Андроида все прекрасно , но Microsoft стал меня по моему блокировать вот бессовестные . не стыда не совести
Я НЕ понимаю ОТКУДА ТАКОЙ РЕЙТИНГ и столько хвалебных од !!!! ???????? А,вообще то понимаю - БОЛЬШИНСТВО отзывов КУПЛЕННЫЕ - 100% !!!!!!!!!! Расширение НЕ РАБОТАЕТ - от слова СОВСЕМ!!!!!!!!!!! ВСЕ САЙТЫ ПРОВЕРКИ User-Agent'а ОПРЕДЕЛЯЮТ РЕАЛЬНЫЕ ДАННЫЕ НА 100500% !!!!!!!!!!!!!!
Not work
I'm still giving this 5/5 stars even though it could use some way of updating the preinstalled UA strings to newest versions, but honestly, finding those strings are just a search away. Setting UA to "Chrome" clears the UA string, which on other Chromium based browsers is a bit confusing, but once you get used to it, it's no problem at all. Being able to add your own UA strings is great, you can test all the versions you want problem free - once you know how to edit them.
