You don't need this in Ruby 1.9

Have a look at this:

This just creates an instance of firefox with a temp profile which can 
be controlled via Selenium-webdriver

The element on the page with the name "q" happens to be the search text 
field. I recommend using Firebug to find out what each element can be 
identified by.

Watir-webdriver's latest version has waiting built-in, it looks like 
Selenium has a seperate wait module.

You're passing a block to the wait module, until method which will stop 
waiting once it evaluates to "true". This waits until the page has 
loaded to a point that it has changed the title of the browser window.

I'm not sure about Selenium, but with watir-webdriver using "close" 
rather than "quit" cleans up the temp files as well.

This is what the same sequence looks like with watir-webdriver:

require 'watir-webdriver'
driver = Watir::Browser.new :firefox
driver.goto "http://google.com"
element = driver.text_field(:name => "q")
element.set "Cheese!\n"
puts "Page title is #{driver.title}"
driver.wait_until { driver.title.downcase.start_with? "cheese!" }
puts "Page title is #{driver.title}"
driver.close
