Proof of concept Marionette, the next generation of FirefoxDriver.

Install recent firefox

Download recent firefox, for instance latest aurora, and install.

$ wget https://download-installer.cdn.mozilla.net/pub/firefox/nightly/latest-mozilla-aurora/firefox-49.0a2.en-US.linux-x86_64.tar.bz2
$ tar xjf firefox-49.0a2.en-US.linux-x86_64.tar.bz2
$ mv firefox firefox-latest
$ sudo mv firefox-latest /opt/

Install geckodriver

Download latest geckodriver and copy it to a dir in the PATH. As of selenium==2.53.6 it is necessary to add an alias as wires.

$ wget https://github.com/mozilla/geckodriver/releases/download/v0.9.0/geckodriver-v0.9.0-linux64.tar.gz
$ tar xzf geckodriver-v0.9.0-linux64.tar.gz
$ sudo cp geckodriver /usr/local/bin/
$ sudo ln -s /usr/local/bin/geckodriver /usr/local/bin/wires

Finally, configure selenium code:

from selenium import webdriver
from selenium.webdriver.common.desired_capabilities import DesiredCapabilities

caps = DesiredCapabilities.FIREFOX
caps["marionette"] = True
caps["binary"] = "/opt/firefox-latest/firefox"

driver = webdriver.Firefox(capabilities=caps)

driver.get("http://www.python.org")
assert "Python" in driver.title
