don't store any static path

use following code this will automatically install the web-driver if not installed

from webdriver_manager.firefox import GeckoDriverManager
def get_driver():
    options = Options()
    options.headless = True
    driver = webdriver.Firefox(
        executable_path=GeckoDriverManager().install(), options=options)
    return driver
