How can I set a default profile for the Firefox driver in Selenium Webdriver 3?

As you are using Selenium 3.14.0 as per the FirefoxDriver Class the valid constructors are:

• FirefoxDriver()
• FirefoxDriver(FirefoxOptions options)
• FirefoxDriver(GeckoDriverService service)
• FirefoxDriver(GeckoDriverService service, FirefoxOptions options)
• FirefoxDriver(XpiDriverService service)
• FirefoxDriver(XpiDriverService service, FirefoxOptions options)

So, as per your code attempts the following is not a valid option to invoke FirefoxDriver()

WebDriver driver = new FirefoxDriver(profile);

Solution

To invoke invoke FirefoxDriver() with the default profile you need to use the setProfile(profile) method to set the FirefoxProfile through an instance of FirefoxOptions() and you can use the following code block:

• Code Block:

  import org.openqa.selenium.WebDriver;
  import org.openqa.selenium.firefox.FirefoxDriver;
  import org.openqa.selenium.firefox.FirefoxOptions;
  import org.openqa.selenium.firefox.FirefoxProfile;
  import org.openqa.selenium.firefox.ProfilesIni;
  import org.testng.annotations.Test;
  
  public class A_FirefoxProfile {
  
        @Test
        public void seleniumFirefox() {
          System.setProperty("webdriver.gecko.driver", "C:/Utility/BrowserDrivers/geckodriver.exe");
          ProfilesIni profileIni = new ProfilesIni();
          FirefoxProfile profile = profileIni.getProfile("default");
          FirefoxOptions options = new FirefoxOptions();
          options.setProfile(profile);
          WebDriver driver = new FirefoxDriver(options);
          driver.get("http://www.google.com");
          System.out.println(driver.getTitle());
        }
  
  }
