How to add DesiredCapabilities to GeckoDriver in Selenium-Java 3.11

Question

Am trying to use GeckoDriver for firefox in selenium-java 3.11. The firefox version is 59. Things are working fine and am able to invoke the firefox driver. The only challenge is I need to add DesiredCapabilities to my firefox instance.

The old method WebDriver driver = new FirefoxDriver(capabilities); in latest selenium version seems to be deprecated and am not able to figure out the new way to specify the capabilities.

Here is the code:

public static WebDriver createDriver(String userAgentKey, String PROXY) {


     File modifyHeaders = null;
     try {
     modifyHeaders =
     ResourceUtils.getFile("classpath:modify_headers-0.7.1.1-fx.xpi");  //am adding the extension using DesiredCapabilities
     } catch (FileNotFoundException e1) {

     e1.printStackTrace();
     }

    Proxy proxy = new Proxy();
    proxy.setHttpProxy(PROXY).setFtpProxy(PROXY).setSslProxy(PROXY);



    FirefoxProfile profile = new FirefoxProfile();
    profile.setPreference("javascript.enabled", true);
    profile.setPreference("brower.link.open_newwindow", 1);


    profile.setPreference("modifyheaders.config.active", true);
    profile.setPreference("modifyheaders.config.alwaysOn", true);
    profile.setPreference("modifyheaders.headers.count", 1);
    profile.setPreference("modifyheaders.headers.action0", "Add");
    profile.setPreference("modifyheaders.headers.name0", "Proxy-Authorization");
    profile.setPreference("modifyheaders.headers.value0", "Basic dnNodWtsYUBleHBlZGlhLmNvbTpxZWxsYWZraw==");
    profile.setPreference("modifyheaders.headers.enabled0", true);

    profile.addExtension(modifyHeaders);

    DesiredCapabilities cap = DesiredCapabilities.firefox();
    cap.setCapability(FirefoxDriver.PROFILE, profile);
    cap.setCapability(CapabilityType.PROXY, proxy);
    System.setProperty("webdriver.gecko.driver","/Users/vshukla/Music/geckodriver");

    WebDriver driver = new FirefoxDriver(cap);  //this is deprecated


    return driver;

How can I add the extension to instance using DesiredCapabilities? What are other options to achieve this?

Use firefox options :

    FirefoxOptions options = new FirefoxOptions();
    options.setCapability(FirefoxDriver.PROFILE, profile);
    options.setCapability(CapabilityType.PROXY, proxy);

Though this gives the right way to set capabilities, still I don't see the extension added to my instance. – roger_that Apr 19 '18 at 09:26
are you talking about profile.addExtension(modifyHeaders); ? – cruisepandey Apr 19 '18 at 09:29
you can use this method also for that purpose : options.setProfile(profile); – cruisepandey Apr 19 '18 at 09:36

You were almost there. You need to use the method merge() from MutableCapabilities Class to merge the DesiredCapabilities type of object into FirefoxOptions type object and initiate the WebDriver and WebClient instance by passing the FirefoxOptions object as follows :

import org.openqa.selenium.WebDriver;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.openqa.selenium.firefox.FirefoxOptions;
import org.openqa.selenium.remote.DesiredCapabilities;

System.setProperty("webdriver.gecko.driver","/Users/vshukla/Music/geckodriver");
DesiredCapabilities cap = DesiredCapabilities.firefox();
cap.setCapability(FirefoxDriver.PROFILE, profile);
cap.setCapability(CapabilityType.PROXY, proxy);
FirefoxOptions opt = new FirefoxOptions();
opt.merge(cap);
WebDriver driver = new FirefoxDriver(opt);

PS : As a reference you can have a look at the discussions in mutablecapabilities tag
