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/.

安装后地址栏用百度搜索会不停刷新，根本无法使用
I use it to switch from the new to the old Twitter UI and it was as a charm :)

Is there any for Mac OSX Mojave? More specifically Mozilla/5.0 (Macintosh; Intel Mac OS X 10_14_1) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/70.0.3538.102 Safari/537.36 Which do I select?
这个有点问题，而且是验证码的问题，大陆有些网站验证码是图片形式的，但是开启UA后就把验证码屏蔽了，不知是神马问题，也许和UBLOCK，ABP有关？？？冲突？
Nice, now i can have old twitter design back, love this extension!
Cumple con lo que dice.
Items added to the Permanent Spoof List are not triggered when going to the site even though "Permanent spoofs always override any user-agent selection in the toolbar." and "Set user-agent spoof per tab" are check marked. example. I have www.twitter.com and twitter.com added. It doesn't change the agent when going to the site. Still set to chrome even after reloading the browser.
이 되도 않는 것 때문에 업무용 사이트가 동작을 안함 주제에 지워지지 않게 되어있어서 크롬을 밀고 새로 설치함
It's so old, it completely useless. most web pages wont even load with this installed.
