selenium-webdriver won't work against Firefox 48 or later about rails-4-1-rspec-3-0 HOT 2 OPEN

Thanks @JunichiIto. My recommendation is to go with PhantomJS/Poltergeist. I wrote about how to switch out selenium-webdriver for poltergeist on Everyday Rails.

from rails-4-1-rspec-3-0.

Also you can use an older version of Firefox, because selenium-webdriver already doesn't work as in previous versions.

Giving the location of the old Firefox version to the binary path you can use it as we've accustomed.

irb(main):001:0> Selenium::WebDriver::Firefox::Binary.path = "/opt/firefox17/firefox"
irb(main):002:0> browser = Capybara::Session.new(:selenium)
irb(main):003:0> browser.visit('http://google.cl')
