Introduction:
The Selenium Server is needed in order to run either Selenium RC style scripts or Remote Selenium WebDriver ones.
Background:
There has been a change to Selenium Builder since this documentation, Selenium Builder 3.0.5 is what now comes with Firefox.
You cannot run locally anymore from Selenium Builder, you need to run from Selenium Server.
Environment:
All Supported DevTest Windows platforms
Firefox browser only can be used for Selenium recording
Instructions:
Selenium Server can be gotten from: http://www.seleniumhq.org/download/
This is just a jar file that gets downloaded and then when you execute the jar file it runs like this example:
C:\SeleniumServer>java -jar selenium-server-standalone-2.50.1.jar
10:34:56.286 INFO - Launching a standalone Selenium Server
