How do I disable Firefox logging in Selenium using Geckodriver?

To not see the logs in the console you can use the following:

System.setProperty("webdriver.gecko.driver","src/main/resources/drivers/geckodriver.exe");System.setProperty(FirefoxDriver.SystemProperty.DRIVER_USE_MARIONETTE,"true");System.setProperty(FirefoxDriver.SystemProperty.BROWSER_LOGFILE,"/dev/null");return new FirefoxDriver();

You can define the desired logging level over command line in geckodriver.exe.

geckodriver.exe -help    USAGE:    geckodriver.exe [FLAGS] [OPTIONS]   ...OPTIONS:        --log <LEVEL>            Set Gecko log level [values: fatal, error, warn, info, config,            debug, trace]

If you use geckodriver from selenium, you have two option:

• Start geckodriver.exe separately with custom arguments, and use it from selenium over RemoteWebDriver
• Create a custom wrapper, to add extra parameters to geckodriver.exe

Example geckodriver wrapper bat file (for windows):

@ECHO OFFECHO Starting geckodriver: %0 %*.\GeckoDriver\geckodriver.exe --log fatal %* > NUL 2>&1

In java you can define the geckodriver executable path, over webdriver.gecko.driver system property:

System.setProperty("webdriver.gecko.driver", "c:/selenium/geckodriver/gdrvwrapper.bat");

Just do this

System.setProperty(FirefoxDriver.SystemProperty.DRIVER_USE_MARIONETTE,"true");System.setProperty(FirefoxDriver.SystemProperty.BROWSER_LOGFILE,"/dev/null");driver = new FirefoxDriver();
