While working with Selenium v3.11.x, GeckoDriver v0.20.0 and Firefox Quantum v59.0.2 there are different option to invoke a new/existing Firefox Profile

If you are looking to use a new Firefox Profile on every run of your Test Execution you can use the following code block :

System.setProperty("webdriver.gecko.driver", "C:\\path\\to\\geckodriver.exe");
FirefoxOptions options = new FirefoxOptions();
options.setProfile(new FirefoxProfile());
WebDriver driver = new FirefoxDriver(options);
driver.get("https://www.google.com");

If you are looking to use an existing Firefox Profile on every run of your Test Execution first you have to create a Firefox Profile manually following the instructions at Creating a new Firefox profile on Windows.

Now you have 2 ways to invoke the Firefox Profile you have created as follows :

• You can use the FirefoxOptions class to invoke the existing Firefox Profile and you can use the following code block :

  System.setProperty("webdriver.gecko.driver", "C:\\path\\to\\geckodriver.exe");
  ProfilesIni profile = new ProfilesIni();
  FirefoxProfile testprofile = profile.getProfile("debanjan");
  FirefoxOptions opt = new FirefoxOptions();
  opt.setProfile(testprofile);
  WebDriver driver =  new FirefoxDriver(opt);
  driver.get("https://www.google.com");
  

• You can also use the DesiredCapabilities class to set the existing Firefox Profile and later merge within an instance of FirefoxOptions and you can use the following code block :

  System.setProperty("webdriver.gecko.driver", "C:\\path\\to\\geckodriver.exe");
  ProfilesIni profile = new ProfilesIni();
  FirefoxProfile testprofile = profile.getProfile("debanjan");
  DesiredCapabilities dc = DesiredCapabilities.firefox();
  dc.setCapability(FirefoxDriver.PROFILE, testprofile);
  FirefoxOptions opt = new FirefoxOptions();
  opt.merge(dc);
  WebDriver driver =  new FirefoxDriver(opt);
  driver.get("https://www.google.com");
