Hi

I want to run test capybara with gem ‘selenium-webdriver’. I installed firefox on cloud 9 with following comand: sudo apt-get install firefox xvfb

I run test: xvfb-run --auto-servernum rspec spec/features/my_test_spec.rb

and get error: **(firefox:5362): Gdk-WARNING : firefox: Fatal IO error 11 (Resource temporarily unavailable) on X server :99.

Its possible test capybara with library selenium with firefox in cloud 9?
