Selenium Proxy on Grid - selenium

Question

I have this setup that is setting proxy ok in the local browser but when i try to use the grid the proxy will not be sent to the node:
var driver = new webdriver.Builder()
.withCapabilities(webdriver.Capabilities.firefox())
.setProxy(proxy.manual({ http : 'proxy:port',
https : 'proxy:port',
}))
.build();
Result : the browser proxy is - proxy:port ;
When i add :
var driver = new webdriver.Builder()
.withCapabilities(webdriver.Capabilities.firefox())
.setProxy(proxy.manual({ http : 'proxy:port',
https : 'proxy:port',
}))
.usingServer('http://hub:port/wd/hub')
.build();
The result : the browser proxy is - it showes me the ip of the hub.
Question : does anyone knows why the proxy set manualy is not sent to the hub and why the browser doesn't use it ? Or any other solution for this problem ?

Answer 1

This is the solution that worked :
var webdriver = require('selenium-webdriver'),
firefox = require('selenium-webdriver/firefox'),
proxy = require('selenium-webdriver/proxy')
driver = null,
profile = new firefox.Profile();
profile.setPreference("network.proxy.type", 1); // Manual proxy config
profile.setPreference("network.proxy.http", "proxy");
profile.setPreference("network.proxy.http_port", port);
profile.setPreference("network.proxy.ssl", "proxy");
profile.setPreference("network.proxy.ssl_port", port);
var opts = new firefox.Options();
opts.setProfile(profile);
var driver = new webdriver.Builder()
.withCapabilities(webdriver.Capabilities.chrome())
.setFirefoxOptions(opts);
.build();
