Using Selenium 3.4.x, Python 3.6.1 along with geckodriver v0.16.1 & Mozilla Firefox 53.0, you can use the existing Firefox profile through the following steps:

1. Locate the Firefox Profile directory on your windows box. For e.g. my Firefox Profile "debanjan" was located at C:\\Users\\AtechM_03\\AppData\\Roaming\\Mozilla\\Firefox\\Profiles by the name w8iy627a.debanjan.
2. Next, you have to specify the absolute path of the Firefox Profile directory when you initiate the webdriver.

3. Here is the working code which opens an existing Firefox Profile 'debanjan' on my Windows machine:

   It is to be noted that the current Selenium-Python binding is unstable with geckodriver and looks to be Architecture specific. You can find the github discussion and merge here. So you may additionally need to pass the absolute path of the firefox binary while initializing the webdriver

   from selenium import webdriver
   from selenium.webdriver.firefox.firefox_binary import FirefoxBinary
   
   profile = webdriver.FirefoxProfile('C:\\Users\\AtechM_03\\AppData\\Roaming\\Mozilla\\Firefox\\Profiles\\w8iy627a.debanjan')
   binary = FirefoxBinary('C:\\Program Files\\Mozilla Firefox\\firefox.exe')
   
   driver = webdriver.Firefox(firefox_profile=profile, firefox_binary=binary, executable_path="C:\\Utility\\BrowserDrivers\\geckodriver.exe")
   url = 'https://www.paininneck.co.uk'
   driver.get(url)
