How to Disable Firefox Logging in Selenium with Geckodriver

How can I disable logs generated by Firefox while using Geckodriver in Selenium?

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

service = Service(log_path='nul')
options = webdriver.FirefoxOptions()
with webdriver.Firefox(service=service, options=options) as driver:
    driver.get('http://example.com')

When using Selenium with Geckodriver, you may encounter verbose logging from Firefox, which can clutter your terminal or logs. Disabling this logging can lead to cleaner outputs and improved performance. In this guide, we will show you how to achieve that effectively.

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

# Suppress Firefox logs by directing them to 'nul'
service = Service(log_path='nul')
options = webdriver.FirefoxOptions()

# Create a new instance of the Firefox driver
with webdriver.Firefox(service=service, options=options) as driver:
    driver.get('http://example.com')
    # Your Selenium automation code here
    
# The above code will run without excessive logging.

Causes

• Geckodriver generates logs by default to help debug issues.
• Logs can make terminal output cluttered, especially in automated testing.

Solutions

• Set the `log_path` parameter to a null device to suppress logs.
• Use Firefox options to configure logging settings.

Mistake: Forgetting to import necessary modules for Service and Options.

Solution: Ensure to import from selenium.webdriver.firefox.service and selenium.webdriver.FirefoxOptions.

Mistake: Not configuring Geckodriver correctly, which leads to still seeing logs.

Solution: Always set the correct log path using 'nul' on Windows or '/dev/null' on Unix systems.
