Watir browser process doesn't start properly (Windows)

I've built a simple script in Linux, but now I'm trying to get it to work on windows.

The code is:

require 'watir-webdriver'
puts "Press enter when ready to continue"
gets
browser = Watir::Browser.start "http://www.google.com"
# do stuff

It works exactly as expected on Ubuntu. But when I try it on Windows, the Firefox process starts, but then dies before you even see a Firefox window. This is a fresh install of Ruby on this Windows installation, I've never used it before on this machine.

What could be the problem?

Edit: Command line trace, as requested.

That's this bug in Firefox. Your options are:

  1. Wait for the patch in Firefox 47
  2. Downgrade to Firefox 46
  3. Use Marionette instead of the Firefox Driver (which is being deprecated and won't work with new versions of Firefox soon)
  4. Use Chrome

To try marionette, download the geckodriver and do:

browser = Watir::Browser.new :firefox, marionette: true
