Global variables should be available in all modules and in all files. You could put this global variable in a file named (for example) common.rb and require or load that file in all of your scripts.

But you don't need to use a global variable. You could just as easily do something like this and load it in every script file that you need.

module Browser
  def self.ie
    @ie ||= Watir::IE.new_process
  end
end
