selenium web driver giving error 'Fire fox has stopped working' while opening firefox window

[Anup-Deo21]

below is my code for Assign1.py file

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

create a new Firefox session

driver = webdriver.Firefox()
driver.implicitly_wait(30)
driver.maximize_window()

navigate to the application home page

driver.get("http://www.google.com")

get the search textbox

search_field = driver.find_element_by_id("lst-ib")
search_field.clear()

enter search keyword and submit

search_field.send_keys("Selenium WebDriver Interview questions")
search_field.submit()

get the list of elements which are displayed after the search

currently on result page using find_elements_by_class_name method

lists = driver.find_elements_by_class_name("_Rm")

get the number of elements found

print str(len(lists))

iterate through each element and print the text that is

name of the search

i = 0
for listitem in lists:
print (listitem)
i = i + 1
if (i > 10):
break

close the browser window

driver.quit()

After running the code using

Python Assign1.py

it is showing following error while opening fire fox browser

After clicking on close program it showing following errors on command prompt:
