python – Problems using the Selenium module with Firefox

J & # 39; uses:

  • Debian version 9.6
  • Python 2.7
  • Selenium 3.141.0
  • Firefox 60.3.0

I'm trying to learn how to use Selenium with Python, but I still have not been able to do anything. Always give an error, I correct that I found the solutions but in the last I can not.
