Connecting to the Tor network with Python without getting "Proxy server is refusing connection"

I've been trying to use Tor via Python only to come across the "Proxy server is refusing connection" error.

I've trying this method using the Stem library: http://www.thedurkweb.com/automated-anonymous-interactions-with-websites-using-python-and-tor/

Any help to fixing this error?

Here is the code:

import stem.process
from stem import Signal
from stem.control import Controller
from splinter import Browser

proxyIP = "127.0.0.1"
proxyPort = 9150

proxy_settings = {"network.proxy.type":1,
    "network.proxy.ssl": proxyIP,
    "network.proxy.ssl_port": proxyPort,
    "network.proxy.socks": proxyIP,
    "network.proxy.socks_port": proxyPort,
    "network.proxy.socks_remote_dns": True,
    "network.proxy.ftp": proxyIP,
    "network.proxy.ftp_port": proxyPort
}
browser = Browser('firefox', profile_preferences=proxy_settings)

def interactWithSite(browser):
    browser.visit("http://dogdogfish.com/python-2/generating-b2b-sales-data-in-python/")
    browser.fill("comment", "But the thing is... Why would anyone ever want to do this? I must have thought that times...")
    browser.fill("author", "Pebblor El Munchy")
    browser.fill("email", "barack@tehwhitehouz.gov")
    browser.fill("url", "https://upload.wikimedia.org/wikipedia/en/1/16/Drevil_million_dollars.jpg")
    button = browser.find_by_name("submit")
    button.click()

interactWithSite(browser)

Solution

I deleted the SSL and FTP proxy and port settings and it worked. I also used port 9150.

Here is the working code:

import stem.process
from stem import Signal
from stem.control import Controller
from splinter import Browser

proxyIP = "127.0.0.1"
proxyPort = 9150

proxy_settings = {"network.proxy.type":1,
    "network.proxy.socks": proxyIP,
    "network.proxy.socks_port": proxyPort,
    "network.proxy.socks_remote_dns": True,
}
browser = Browser('firefox', profile_preferences=proxy_settings)

def interactWithSite(browser):
    browser.visit("http://dogdogfish.com/python-2/generating-b2b-sales-data-in-python/")
    browser.fill("comment", "But the thing is... Why would anyone ever want to do this? I must have thought that times...")
    browser.fill("author", "Pebblor El Munchy")
    browser.fill("email", "barack@tehwhitehouz.gov")
    browser.fill("url", "https://upload.wikimedia.org/wikipedia/en/1/16/Drevil_million_dollars.jpg")
    button = browser.find_by_name("submit")
    button.click()

interactWithSite(browser)
