title: Problem in Find Element after page changed in Selenium Python
body: <p>im using a web scraper library as [Selenium] in python.
  and i want to submit a form (multiple form without AJAX)</p>
  
  <p>so , i wrote this code :</p>
  
  <pre><code>from selenium import webdriver
  import time
  
  driver = webdriver.Chrome()
  driver.get('https://exportgram.com/')
  
  one = driver.find_element_by_xpath('//*[@id="home"]/form/div[1]/div/input[1]')
  one.click()
  one.send_keys('https://www.instagram.com/p/B6OCVnTglgz/')
  two = driver.find_element_by_xpath('//*[@id="home"]/form/div[2]/button')
  two.click()
  time.sleep(3)
  
  
  three = driver.find_element_by_xpath('//*[@id="home"]/form/div[2]/button')
  three.click()
  </code></pre>
  
  <p>now , i cant access "three" because thats available on new page.</p>
  
  <p>isnt any way to resolve that problem?</p>
  
  <p>[Note : after click on 'two' , page changed to '<a href="https://example.com/media.php" rel="nofollow noreferrer">https://example.com/media.php</a>']</p>
