Answer 1

Could be due to synchronization issue try to induce WebDriverWait:

wait = WebDriverWait(driver, 20)

wait.until(EC.element_to_be_clickable((By.XPATH, "//*[@id='mount_0_0']/div/div/div[1]/div[3]/div/div[1]/div/div/ul/li[2]/span/div/a"))).click()
wait.until(EC.element_to_be_clickable((By.XPATH, "//*[@id='mount_0_0'']/div/div/div[2]/div/div/div/div/div/div[2]/div/div/div/div[3]/div/div/div[1]/div/a/span"))).click()

Note: please add below imports to your solution

from selenium.webdriver.support import expected_conditions as EC
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait

After checking on the Facebook website, '//*[@id="mount_0_0"]' is the xpath of the main container. For the button you are trying to click, the xpath I have found is:

//*[@id="mount_0_0"]/div/div/div[1]/div[3]/div/div[1]/div/div/ul/li[2]/span/div/a

Maybe you could try with this one?
