Setup proxy in Firefox browser via marionette driver - selenium

Question

Firefox 47 and above do not support Selenium Webdriver. I tried to use a Marionette driver to start my tests via Firefox.
But my settings in firefox-profile (proxy must set to network.proxy.type = 4, auto-detect) is no longer applied to Firefox config (Firefox opens but all settings set by default) and my tests do not work without the right PROXY configuration.
How can I setup proxy in Firefox browser via a Marionette driver?

Answer 1

The old tricks with firefoxProfile or Proxy class do not work any more. All you have to do is pass through requiredCapabilities a JSON with the new Marionette proxy format:
[{proxy={"proxyType":"MANUAL","httpProxy":"host.proxy","httpProxyPort":80,"sslProxy":"host.proxy","sslProxyPort":80}}]
No more "proxyHost:proxyPort" format, but httpProxy=host, httpProxyPort=port.
JsonObject json = new JsonObject();
json.addProperty("proxyType", "MANUAL");
json.addProperty("httpProxy", aHost);
json.addProperty("httpProxyPort", aPort);
json.addProperty("sslProxy", aHost);
json.addProperty("sslProxyPort", aPort);
required.setCapability("proxy", json);
driver = new FirefoxDriver(service, cap, required);

int proxyPort = Integer.parseInt(args[1]);
