How to turn off the Marionette/gecko driver logs in selenium 3

You can disable the logs by sending them to /dev/null via a system property like so:

System.setProperty(FirefoxDriver.SystemProperty.BROWSER_LOGFILE,"/dev/null");return new FirefoxDriver();

Working solution on Windows and Linux.

# python 3# windowsPATH_TO_DEV_NULL = 'nul'FIREFOX_DRIVER_PATH = 'D:\\path\\to\\geckodriver.exe'# linuxPATH_TO_DEV_NULL = '/dev/null'FIREFOX_DRIVER_PATH = '/path/to/geckodriver'# start browserdriver = webdriver.Firefox(executable_path=FIREFOX_DRIVER_PATH,                           service_log_path=PATH_TO_DEV_NULL)

Tried the following code, but didn't work. Seems like a bug in selenium 3.0

    LoggingPreferences pref = new LoggingPreferences();    pref.enable(LogType.BROWSER, Level.OFF);    pref.enable(LogType.CLIENT, Level.OFF);    pref.enable(LogType.DRIVER, Level.OFF);    pref.enable(LogType.PERFORMANCE, Level.OFF);    pref.enable(LogType.PROFILER, Level.OFF);    pref.enable(LogType.SERVER, Level.OFF);    DesiredCapabilities desiredCapabilities = DesiredCapabilities.firefox();    desiredCapabilities.setCapability(CapabilityType.LOGGING_PREFS, pref);    WebDriver driver = new FirefoxDriver(desiredCapabilities);    driver.get("https://www.google.com/");    driver.findElement(By.id("lst-ib")).sendKeys("something");    Thread.sleep(2000);    driver.quit();
