据我所知，只有两种方法来更改代理设置，一个通过配置文件），而另一个使用驱动程序的功能时，按照此处进行实例化。可悲的是，这些方法都没有做你想要的，因为它们都是在你创建驱动程序之前发生的。

我必须问，为什么要更改代理设置？我唯一可以想到的唯一解决方案就是将firefox指向可以在运行时更改的代理。我不确定，但这可能是与browsermob代理可能。

Is there any way to dynamically change the proxy being used by Firefox when using selenium webdriver?

Currently I have proxy support using a proxy profile but is there a way to change the proxy when the browser is alive and running?

My current code:

proxy = Proxy({
    'proxyType': 'MANUAL',
    'httpProxy': proxy_ip,
    'ftpProxy': proxy_ip,
    'sslProxy': proxy_ip,
    'noProxy': '' # set this value as desired
    })
browser = webdriver.Firefox(proxy=proxy)

Thanks in advance.

As far as I know there are only two ways to change the proxy setting, one via a profile (which you are using) and the other using the capabilities of a driver when you instantiate it as per here. Sadly neither of these methods do what you want as they both happen before as you create your driver.

I have to ask, why is it you want to change your proxy settings? The only solution I can esily think of is to point firefox to a proxy that you can change at runtime. I am not sure but that might be possible with browsermob-proxy.
