When MarionetteDriver is launched it's print log statement for each and every operation.Like
1465882610065 Marionette TRACE conn0 -> [0,138,"executeScript",{"args":[],"newSandbox":false,"script":"return Math.max(document.body.scrollHeight, document.documentElement.scrollHeight,document.body.offsetHeight, document.documentElement.offsetHeight,document.body.clientHeight, document.documentElement.clientHeight);","scriptTimeout":null,"specialPowers":false}]
1465882610066 Marionette TRACE conn0 <- [1,138,null,{"value":895}]
1465882610070 Marionette TRACE conn0 -> [0,139,"executeScript",{"args":[],"newSandbox":false,"script":"window.devicePixelRatio = window.devicePixelRatio || window.screen.deviceXDPI / window.screen.logicalXDPI; var pr = window.devicePixelRatio; if (pr != undefined && pr != null) return pr; else return 1.0;","scriptTimeout":null,"specialPowers":false}]
1465882610071 Marionette TRACE conn0 <- [1,139,null,{"value":1}]
1465882610319 Marionette TRACE conn0 -> [0,140,"findElements",{"using":"css selector","value":".logOut"}]

And I'm launching the MarionetteDriver by
System.setProperty("webdriver.gecko.driver", "geckodriver.exe");
WebDriver driver = new MarionetteDriver();
Is there any capabilities to disable the logs
回答1:
Firefox is supposed to have an option to set the logging level for Marionette in the about:config property marionette.logging, but this apparently is not present in builds up to and including 47.
Apparently Marionette is not officially supported in build 47, which is unfortunate because FirefoxDriver also no longer works on this build either. Currently the only supported options are to downgrade (and use FirefoxDriver) or wait for updates.
It is theorized that this will be fixed in 47.0.1 or 48 and might already be in the nightlies.

You can use the following lines of code to not display the marionette logs:
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();

Here are all the ways I've seen to do it online, the only part that seems to do ANYTHING AT ALL is setting the browser log file to /dev/null :(
// ----------- BEGIN NIGHTMARISH AMOUNT OF CODE TO SET THE LOG LEVEL ------------
boolean detailedLogs = false;
File profileDirectory = new File(Settings.FireFoxProfilePath);
System.setProperty("webdriver.gecko.driver", "Drivers/geckodriver-linux64");
//System.setProperty("webdriver.gecko.driver","src/main/resources/drivers/geckodriver.exe");
if (!detailedLogs) {
System.setProperty(FirefoxDriver.SystemProperty.DRIVER_USE_MARIONETTE, "true");
System.setProperty(FirefoxDriver.SystemProperty.BROWSER_LOGFILE, "/dev/null");
}
FirefoxProfile profile = null;
FirefoxOptions options = new FirefoxOptions();
if (profileDirectory.exists()) {
profile = new FirefoxProfile(profileDirectory);
profile.setPreference("marionette.log.level", detailedLogs?"trace":"warn");
profile.setPreference("marionette.logging", detailedLogs);
options.setProfile(profile);
}
options.setLogLevel(FirefoxDriverLogLevel.WARN);
LoggingPreferences logs = new LoggingPreferences();
logs.enable(LogType.BROWSER, detailedLogs? Level.ALL : Level.WARNING);
logs.enable(LogType.CLIENT, detailedLogs? Level.ALL : Level.WARNING);
logs.enable(LogType.DRIVER, detailedLogs? Level.ALL : Level.WARNING);
logs.enable(LogType.PERFORMANCE, detailedLogs? Level.ALL : Level.WARNING);
logs.enable(LogType.PROFILER, detailedLogs? Level.ALL : Level.WARNING);
logs.enable(LogType.SERVER, detailedLogs? Level.ALL : Level.WARNING);
//LEGACY: DesiredCapabilities desiredCapabilities = DesiredCapabilities.firefox();
//desiredCapabilities.setCapability(CapabilityType.LOGGING_PREFS, logs);
options.setCapability(CapabilityType.LOGGING_PREFS, logs);
options.addPreference("extensions.logging.enabled", false);
options.addPreference("marionette.log.level", detailedLogs?"trace":"warn");
options.addPreference("marionette.logging", detailedLogs); // from https://github.com/mozilla/geckodriver/issues/89
// ----------- END NIGHTMARISH AMOUNT OF CODE TO SET THE LOG LEVEL ------------
driver = new FirefoxDriver(options);
