Modify logging level on Selenium Firefox driver?

I'm running tests for a Java/Maven project using Selenium 3.4 and the FirefoxDriver (not the Marionette/Geckodriver). I have Firefox 45.9.0 installed. Our test code uses Log4j2 and I can set the logging level to whatever I like, but no matter what I set it to I get log messages like this in the console:

It looks like something inside the FirefoxDriver, or inside Firefox itself, is logging at a DEBUG level no matter what I set our logging level to.

I looked at this question but I can't figure out how to translate the Python answer to our Java code:

Example Python:

import logging
from selenium.webdriver.remote.remote_connection import LOGGER
LOGGER.setLevel(logging.WARNING)

Our Java code:

DesiredCapabilities capability = DesiredCapabilities.firefox();
FirefoxProfile profile=new FirefoxProfile();
capability.setCapability(FirefoxDriver.PROFILE, profile);
mDriver = new FirefoxDriver(capability);

I've tried several permutations but nothing seems to affect this logging - these messages appear in the console no matter what. Anyone have any way to control this logging?

Sorry to dig up an old thread but just wanted to give an updated solution (latest driver version is 0.23.0 as of writing).

Official Docs: https://firefox-source-docs.mozilla.org/testing/geckodriver/geckodriver/TraceLogs.html

Here's the Java example in the documentation above. You can specifiy the logging level by including it in the .setLogLevel method of FirefoxOptions class.

FirefoxOptions options = new FirefoxOptions();
options.setLogLevel(FirefoxDriverLogLevel.TRACE);
WebDriver driver = new FirefoxDriver(options);

You can refer to the documentation for the different levels of logging.
