Answer 1

If you using selenium webdriver from Capybara/Cucumber, then you can change the default url when you register your driver using startup.homepage_welcome_url.additional:

Capybara.register_driver :firefox do |app|
  profile = Selenium::WebDriver::Firefox::Profile.new
  profile['browser.startup.homepage_override.mstone'] = 'ignore'
  profile['startup.homepage_welcome_url.additional'] = 'about:blank'

  Capybara::Selenium::Driver.new(app, :browser => :firefox, :profile => profile)
end
