When I run this script:

from selenium.webdriver.common.keys import Keys
import time

browser = webdriver.Remote('http://localhost:4444/wd/hub', {'browser_name':'firefox','platform':'ANY', 'version':'','javascript_enabled':True})
browser.get("http://www.yahoo.com")

The Selenium server seems to work at first:

00:17:08.776 INFO - Executing: [new session: {platform=ANY, browser_name=firefox, javascript_enabled=true, version=}] at URL: /session)

But then I get a python error:

Traceback (most recent call last):

    browser = webdriver.Remote('http://localhost:4444/wd/hub', {'browser_name':'firefox','platform':'ANY', 'version':'','javascript_enabled':True})

    Looks like you’re using Selenium Grid. The grid consists of a hub and nodes which connect to it. When you run a test you send a request to the server which dispatches it accordingly to a host with the appropriate configuration according to what you defined in desired_capabilities. In this case you don’t seem to have started a node anywhere.

    You have failed to start a node it seems. Also I believe to use a WebDriver requires Grid 2.0. As I understand it, the build you are using only has Grid support for RC API. You can use the following guide if you download and compile the current trunk:
