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

Question

I need to turn off the Marionette/GeckoDriver logging; is there is any way to do that? I've been searching a lot, but I am not getting the proper answer. The INFO logs were:

 1484653905833  geckodriver INFO    Listening on 127.0.0.1:15106

How do I turn off this logging?

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();

This worked for me, even with omitting the DRIVER_USE_MARIONETTE line – nikodaemus Apr 05 '18 at 14:07

Working solution on Windows and Linux.

# python 3

# windows
PATH_TO_DEV_NULL = 'nul'
FIREFOX_DRIVER_PATH = 'D:\\path\\to\\geckodriver.exe'

# linux
PATH_TO_DEV_NULL = '/dev/null'
FIREFOX_DRIVER_PATH = '/path/to/geckodriver'

# start browser
driver = 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();

Even I tried the same. I think it is a bug in gecko driver, will wait for the next release. – Suresh Kumar Jan 19 '17 at 06:54
I suppose that is the same of: firefoxOptions.setLogLevel(Level.OFF); capabilities.setCapability("moz:firefoxOptions", firefoxOptions); – yucer Aug 03 '17 at 11:32

Is there a bug report? Has this been fixed? – Jonathan Sep 22 '18 at 22:00

As of 2022, still doesn't work. – Yan King Yin Jan 18 '22 at 07:49

One option that has worked for some is proposed here, and uses a batch file to pass in command line arguments to the executable. Unfortunately, this oftentimes leaves extra processes open (geckodriver.exe, cmd.exe) and no solution to this next problem has been proposed as of yet...

  GeckoDriverService gecko = new GeckoDriverService(new File("c:/selenium/geckodriver.exe"), 4444, ImmutableList.of("--log=fatal"), ImmutableMap.of());
  gecko.sendOutputTo(new FileOutputStream("gecko_log.txt"));
  gecko.start();

  FirefoxOptions opts = new FirefoxOptions().setLogLevel(Level.OFF);
  DesiredCapabilities capabilities = opts.addTo(DesiredCapabilities.firefox());
  capabilities.setCapability("marionette", true);
  FirefoxDriver driver = new FirefoxDriver(gecko, capabilities);

This might be a bit hacky but it can quickly get the job done. Given that you know the exact location of your file and you run your code on Linux you can just cd into that dir and

rm geckodriver.log
ln -s /dev/null geckodriver.log

service_log_path seems to be deprecated in python:

driver.py:77: DeprecationWarning: service_log_path has been deprecated, please pass in a Service object

This worked for me now:

from selenium.webdriver.firefox.service import Service as FirefoxService
from selenium import webdriver

service = FirefoxService(driver_path, log_path='nul') # Disable logs in windows, for linux probably /dev/null

driver = webdriver.Firefox(
    service=service
)
