A quick way to create an attribute on your ActiveRecord models that always responds with a boolean value, similar to the Boolean attributes from a table that have the ? method for syntactic sugar.
class SomeObject < ActiveRecord::Base
acts_as_boolean :is_active
end
o = SomeObject.new
o.is_active? # => false

We recently were working on a project where the version of Firefox on the development machines was causing acceptance tests running on Capybara and Selenium to fail and/or hang erroneously. The solution was to point Selenium at a custom version of Firefox. We also added the Firefox binaries to the application git repo so that all devs could run against a known good version of Firefox.
Download the desired version of Firefox from ftp://ftp.mozilla.org/pub/firefox/releases/
Put Firefox.app in your rails app somewhere like ./bin/spec/macosx/
