FileExistsError when trying to reuse FirefowProfile

I've been getting the following error while trying to reuse a cached FirefowProfile:

  File "autominer/mine.py", line 20, in __init__
    self.driver = webdriver.Firefox(firefox_profile=ffprofile)
  File "/var/virtual_envs/autominer/lib/python3.4/site-packages/selenium/webdriver/firefox/webdriver.py", line 77, in __init__
    self.binary, timeout),
  File "/var/virtual_envs/autominer/lib/python3.4/site-packages/selenium/webdriver/firefox/extension_connection.py", line 49, in __init__

  File "/var/virtual_envs/autominer/lib/python3.4/site-packages/selenium/webdriver/firefox/firefox_binary.py", line 175, in _modify_link_library_path
    self.profile, self.NO_FOCUS_LIBRARY_NAME, "x86", "amd64")
  File "/var/virtual_envs/autominer/lib/python3.4/site-packages/selenium/webdriver/firefox/firefox_binary.py", line 189, in _extract_and_check
    os.makedirs(library_path)
  File "/var/virtual_envs/autominer/lib/python3.4/os.py", line 237, in makedirs
    mkdir(name, mode)
FileExistsError: [Errno 17] File exists: '/tmp/tmpd3gzuv8g/webdriver-py-profilecopy/x86'

I just added a line checking if the directory exists before trying to create it to the code.Tthe problem is gone here.
