selenium-webdriver doesn't work problem #6

  Capybara.register_driver :selenium_with_firebug do |app|
    profile = Selenium::WebDriver::Firefox::Profile.new
    profile.frame_position = ENV['DRIVER'] && ENV['DRIVER'][2]
    profile.enable_firebug
    Capybara::Selenium::Driver.new(app, :browser => :firefox, marionette: true)
  end

The profile can not pass to Capybara::Selenium::Driver.new.
It was Capybara::Selenium::Driver.new(app, :browser => :firefox, :profile => profile)
but Firefox updated and Selenium updated for marionette.
So I looking for how figure it out and I change that code like that and spec test work now.
But firebug no more enable.

I'm sorry for my bad English.
