Selenium – MoveTargetOutOfBoundsException with Firefox

Issue

I’v got problem with function move_to_element on Firefox Webdriver (Chrome, IE works well)

driver = webdriver.Firefox()
driver.get("https://stackoverflow.com")
time.sleep(5)
source_element = driver.find_element_by_xpath('//*[@id="footer"]/div/ul/li[1]/a')
ActionChains(driver).move_to_element(source_element).perform()

I am working with these versions: geckodriver – 0.17.0 // Firefox – 54.0 // selenium – 3.4.3

After running this script, on output shows:

selenium.common.exceptions.MoveTargetOutOfBoundsException: Message: (134.96666717529297, 8682.183013916016) is out of bounds of viewport width (1268) and height (854) 

Solution

This error…

selenium.common.exceptions.MoveTargetOutOfBoundsException: Message: (134.96666717529297, 8682.183013916016) is out of bounds of Viewport width (1268) and height (854)

…implies that the element you are looking for is not within the Viewport. We need to scroll down to bring the element within the Viewport. Here is the working code:

from selenium import webdriver
from selenium.webdriver.firefox.firefox_binary import FirefoxBinary
from selenium.webdriver.common.desired_capabilities import DesiredCapabilities
from selenium.webdriver.common.action_chains import ActionChains

binary = FirefoxBinary('C:\\Program Files\\Mozilla Firefox\\firefox.exe')
caps = DesiredCapabilities().FIREFOX
caps["marionette"] = True
driver = webdriver.Firefox(capabilities=caps, firefox_binary=binary, executable_path="C:\\Utility\\BrowserDrivers\\geckodriver.exe")
driver.get("https://stackoverflow.com")
last_height = driver.execute_script("return document.body.scrollHeight")
driver.execute_script("window.scrollTo(0, document.body.scrollHeight);")
source_element = driver.find_element_by_xpath('//*[@id="footer"]/div/ul/li[1]/a')
ActionChains(driver).move_to_element(source_element).perform()
