Selenium: No 'moz:firefoxOptions.binary' capability provided, and no binary flag set on the command line

Question

I am running the following Python code with Selenium:

options = Options()
options.binary_location = r'C:\Program Files\Mozilla Firefox\firefox.exe'
options.set_preference('dom.webnotifications.enabled', False)
options.headless = True

driver = webdriver.Firefox(service=FirefoxService(GeckoDriverManager().install()))

and I have ensured that Firefox is installed on my machine and that the executable is in my PATH.

However, I keep getting the following error:

selenium.common.exceptions.SessionNotCreatedException: Message: Expected browser binary location, but unable to find binary in default location, no 'moz:firefoxOptions.binary' capability provided, and no binary flag set on the command line

Please provide enough code so others can better understand or reproduce the problem. — Community

The error you're encountering is because the options object is not being passed to the webdriver.Firefox constructor.

You need to replace this part of your code:

driver = webdriver.Firefox(service=FirefoxService(GeckoDriverManager().install()))

with this:

driver = webdriver.Firefox(service=FirefoxService(GeckoDriverManager().install()), options=options)

I had the same problem.

For me,

I reinstalled Firefox using an offline Installer. ( Apparently, it sets a different path in registry when you install online-install version)
then I set geckodriver.exe as PATH and that fixed the issue.

Hope this helps. cheers

I tried this but it had no effect. I still get the same error.

Add below line before running driver

from selenium.webdriver.firefox.options import Options

options = Options()

options.binary_location = r'C:\Program Files\Mozilla Firefox\firefox.exe'

executable_path='C:\geckodriver'

selenium = WebDriver(executable_path=executable_path, options=options)

This code will run without any error

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

# provide a full path of the driver (replace this with your filepath)
path = r"E:\toor\Tor Browser1\Browser\firefox.exe"

# pass the driver path as a service
service = Service(path)
driver = webdriver.Firefox(service=service)

driver.set_page_load_timeout(30)
driver.get("https://www.google.com/")
driver.quit()
