Answer 1

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 :

System.setProperty("webdriver.gecko.driver", "gecko/linux/geckodriver");

FirefoxProfile profile = new FirefoxProfile();
profile.setPreference("network.proxy.no_proxies_on", "localhost");
profile.setPreference("javascript.enabled", true);

DesiredCapabilities capabilities = DesiredCapabilities.firefox();
capabilities.setCapability("marionette", true);
capabilities.setCapability(FirefoxDriver.PROFILE, profile);

FirefoxOptions options = new FirefoxOptions();
options.merge(capabilities);
options.setLogLevel(Level.FINEST);
options.addPreference("browser.link.open_newwindow", 3);
options.addPreference("browser.link.open_newwindow.restriction", 0);

WebDriver driver = new FirefoxDriver(options);
