Cannot Start The Driver Service On Http Localhost Selenium Firefox C May 2026

On Linux, install xvfb (X Virtual Framebuffer):

Putting GeckoDriver in a folder that is not in your system's PATH environment variable and not specifying the path. If you just write new FirefoxDriver() without a Service object, Selenium will look in PATH and fail if it's not there. Cause 3: Port Conflict or Firewall Blocking The error mentions http://localhost . This is a real network address (127.0.0.1). If something else is using the port range GeckoDriver wants, or if your firewall/antivirus is blocking geckodriver.exe , the service cannot start. Diagnosing Port Conflicts By default, GeckoDriver picks a random free port between 10000 and 60000. If that specific port is locked by another application (like Docker, a local web server, or another WebDriver instance), the bind fails. On Linux, install xvfb (X Virtual Framebuffer): Putting

sudo apt-get install xvfb xvfb-run python your_selenium_script.py Or, use PyVirtualDisplay in Python: This is a real network address (127

from pyvirtualdisplay import Display display = Display(visible=0, size=(1920, 1080)) display.start() # Your Firefox driver code here Sometimes, GeckoDriver starts the HTTP server slowly (slow disk, high CPU). Selenium’s default timeout of 20 seconds expires, and it kills the process. If that specific port is locked by another

For Java:

from selenium import webdriver from selenium.webdriver.firefox.service import Service service = Service(executable_path=r'C:\drivers\geckodriver.exe') driver = webdriver.Firefox(service=service)

Using port=7055 often resolves conflicts because it's a reserved port for WebDriver. On Windows, SmartScreen or Windows Defender may quarantine or silently block geckodriver.exe because it opens a network port (behavior associated with malware).
