title: Cannot run Firefox (geckodriver) properly from PyCharm python console
body: <p>So i use PyCharm 2018.2.3, geckodriver 0.20, Firefox 63.0 and Python 3.6.5 in it for my Selenium auto-tests.</p>
  
  <p>What I try to do in Python Console to run the driver: </p>
  
  <pre><code>from selenium import webdriver
  profile = webdriver.FirefoxProfile()
  profile.accept_untrusted_certs = True
  wd = webdriver.Firefox(executable_path="C:\\Users\\user\\geckodriver.exe", firefox_profile=profile)
  </code></pre>
  
  <p>So the geckodriver runs in a new window. Then I ususally write</p>
  
  <pre><code>url = "https://website-address.com/"
  wd.get(url)
  </code></pre>
  
  <p>But this time I get the message: </p>
  
  <blockquote>
  <pre><code>Previous command is still running. Please wait or press Ctrl+C in console to interrupt.
  </code></pre>
  </blockquote>
  
  <p>And then in like a couple of minutes geckodriver exit with these messages in log:</p>
  
  <blockquote>
  <pre><code>Traceback (most recent call last):

      raise exception_class(message, screen, stacktrace)

  <p>Please help me to understand what is going on and how to fix it.</p>
