browsermob in JAVA with Selenium doesn't work, different errors for browsers

Question

I using Java with selenium and I want to use browsermob: I using same code for different browsers e.g. firefox:

        BrowserMobProxyServer proxyServer = new BrowserMobProxyServer();
        proxyServer.start();
        proxyServer.setHarCaptureTypes(CaptureType.getAllContentCaptureTypes());
        proxyServer.enableHarCaptureTypes(CaptureType.REQUEST_CONTENT, CaptureType.RESPONSE_CONTENT);
        Proxy proxy = ClientUtil.createSeleniumProxy(proxyServer);
        DesiredCapabilities dccFirefox = DesiredCapabilities.firefox();
        dccFirefox.setCapability(CapabilityType.PROXY, proxy);
        this.driver = new FirefoxDriver(dccFirefox);

Occurs error in Firefox:

Chrome open normaly but pages can not be open, in console occurs error:

Failed to load resource: net::ERR_EMPTY_RESPONSE
net::ERR_PROXY_CONNECTION_FAILED

Someone have any idea why this errors occurs?

Answer 1

There is a open a issue with Geckodriver which is causing this issue. https://github.com/mozilla/geckodriver/issues/764

You can get a workaround by using below code.

Edit-1

Since geckodriver the untrusted setting has changed. So updated the code to accommodate the same

import net.lightbody.bmp.BrowserMobProxyServer;
import net.lightbody.bmp.client.ClientUtil;
import net.lightbody.bmp.core.har.Har;
import net.lightbody.bmp.proxy.CaptureType;
import org.openqa.selenium.Proxy;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.openqa.selenium.firefox.FirefoxProfile;
import org.openqa.selenium.remote.DesiredCapabilities;

import java.io.File;
import java.io.IOException;
