What causes a blank page to appear in Firefox upon initial execution with Selenium?

from selenium import webdriver
from selenium.webdriver.common.keys import Keys

driver = webdriver.Firefox()
#driver.set_preference("browser.startup.homepage_override.mstone", "ignore")
driver.get("https://url.aspx/")
username = driver.find_element_by_name("SchSel$txtUserName")
username.clear()
username.send_keys("username")
username.send_keys(Keys.RETURN)
password = driver.find_element_by_name("SchSel$txtPassword")
password.clear()
password.send_keys("pass")
password.send_keys(Keys.RETURN)
driver.get("https://.aspx")
assert "Welcome" in driver.page_source
driver.close()

This is my first time using Selenium. Why does a blank page keep opening in Firefox every time I try to run the script?

selenium.common.exceptions.WebDriverException: Message: The browser appears to have exited before we could connect. If you specified a log_file in the FirefoxBinary constructor, check it for details.
