title: Selenium with Firefox web driver can not find elements by Python code
body: <p>I can not find elements by using Firefox web driver, it print 0:</p>
  
  <pre><code>driver = webdriver.Firefox()
  driver.get("https://www.unibet.ro/betting#filter/football")
  
   event = driver.find_elements_by_class_name('KambiBC-event-item KambiBC-event-item--type-match')
   print (len(event))
  </code></pre>
  
  <p>But it works when I change the web driver to Edge:<code>driver = webdriver.Edge()</code> , as i also have the edge web driver set up in my Path environments, printing the right amount of web elements</p>
