How to extract firefoxdriver from selenium server jar?

Question

I tried moving my project over from my OSX 10.8.5 laptop to a mac mini that uses 10.9.1. Both were setup the same way: cucumber/watir-webdriver/ruby 1.9.3. When I tried to run one feature, I got the following error:

f.QueryInterface is not a function (Selenium::WebDriver::Error::UnknownError)

I downgraded Firefox and watir-webdriver but still was getting the same issue. I read somewhere that running selenium server stand alone installed firefoxdriver xpi. Downloaded/installed java then ran the stand alone selenium server. I stopped selenium server. Ran my feature test again and it ran without any issues. I assume the firefox driver was not installed. I need to setup a couple other people to be able to run the project so I want to avoid downloading/installing java and selenium server just to get it working if possible. Is the firefoxdriver xpi named webdriver.xpi?

The issue turned out to be firefox. Downgraded to an older version and it worked.
