How to change Firefox settings in WebDriver test?

I am running WebDriver tests in Python on Firefox. I have configured my Firefox to make sure all the links of social networking sites are opened in the current tab. I specifically made following two changes

browser.link.open_newwindow.restriction then,  change the value to 0 (zero)
browser.link.open_newwindow and change the value to 1 (one)

It can be found in https://support.mozilla.org/en-US/questions/970999.

My WebDriver Firefox setup consists of 

from selenium.webdriver.firefox.webdriver import WebDriver
from selenium.webdriver.common.action_chains import ActionChains

success = True
wd = WebDriver()
wd.implicitly_wait(60)

How do I also add the settings to the above setup before starting the test code?

Edit

I get the following error when I try to change value of browser.link.open_newwindow

Exception in thread "main" java.lang.IllegalArgumentException: Preference     browser.link.open_newwindow may not be overridden: frozen value=2, requested value=1
    at com.google.common.base.Preconditions.checkArgument(Preconditions.java:120)
    at org.openqa.selenium.firefox.Preferences.checkPreference(Preferences.java:223)
    at org.openqa.selenium.firefox.Preferences.setPreference(Preferences.java:161)
    at org.openqa.selenium.firefox.FirefoxProfile.setPreference(FirefoxProfile.java:230)
    at tmp.main(tmp.java:21)

You can set the preference using a profile like this.

FirefoxProfile profile = new FirefoxProfile();
profile.setPreference("browser.link.open_newwindow.restriction", 0);
profile.setPreference("browser.link.open_newwindow", 1);
WebDriver webDriver =  new FirefoxDriver(profile);

The python code will probably look like this, though I can't test right now.

from selenium import webdriver
profile = webdriver.FirefoxProfile();
profile.set_preference("browser.link.open_newwindow.restriction", 0);
profile.set_preference("browser.link.open_newwindow", 1);
wd =  webdriver.Firefox(profile);
