方便快速切换浏览器 UA (User-Agent) ,并可以自定义 UA 。
但是,很郁闷,它并不能很好的工作:
The user-agent switcher does not modify HTTP headers because the Chrome Extensions API doesn't yet have a way to change them. This means sites like whatismyuseragent.com will not detect a change :( (I will add this as soon as Chrome adds an API for it.) Until Chrome adds this, sites that sniff user-agent strings at the network level will see through the spoofing. Fortunately, most sites just detect the user-agent at the JavaScript level. Also, spoofing the user-agent string does not solve all incompatibilities, and may introduce other incompatibilities.
