Selenium 3 And Firefox 45

Now selenium 3 is the default I’ve had some issues running tests on Centos 6 which use Firefox ESR. Selenium 3 will try and use geckodriver/marionette by default so you have to turn this off. Sample ruby code:

desired_capabilities = Selenium::WebDriver::Remote::Capabilities.firefox
desired_capabilities[:marionette] = false unless system('sh -c "command -v geckodriver > /dev/null"')
Capybara.register_driver(:selenium) { |app| Capybara::Selenium::Driver.new(app, profile: profile, desired_capabilities: desired_capabilities) }
