How to get rid of Firefox logging in Selenium?

After the execution of tests, there are logs generated because of Firefox logging in with geckodriver. This log generation by Firefox can be disabled by certain parameters setting.

We can stop these logs from being recorded in the console and capture them in a different file. This is achieved with the help of the System.setProperty method. In the above image, we can see the geckodriver logs generated in the console.

Syntax

System.setProperty(FirefoxDriver.SystemProperty.DRIVER_USE_MARIONETTE, "true"); // turning off logs

System.setProperty(FirefoxDriver.SystemProperty.BROWSER_LOGFILE, "<path of file>"); // record logs in another file

Example

import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.firefox.FirefoxDriver;
import java.util.concurrent.TimeUnit;
public class LogsDisable{
   public static void main(String[] args) {
      System.setProperty("webdriver.gecko.driver",
      "C:\Users\ghs6kor\Desktop\Java\geckodriver.exe");

      //logging disable
      System.setProperty
      (FirefoxDriver.SystemProperty.DRIVER_USE_MARIONETTE, "true");

      //record log in Firefoxlogs.txt file
      System.setProperty(FirefoxDriver.SystemProperty.BROWSER_LOGFILE,
      "C:\Users\ghs6kor\Desktop\DebomitaJava\Logs\Firefoxlogs.txt");
      WebDriver driver = new FirefoxDriver();

      //implicit wait
      driver.manage().timeouts().implicitlyWait(5, TimeUnit.SECONDS);

      //URL launch
      driver.get("https://www.tutorialspoint.com/about/about_careers.htm");
      System.out.println("Page loaded");
      driver.quit();
   }
}

Output
