Answer 1

Usage of selenium-webdriver behind proxy has browser related specific. In short, you need to find a way of passing proxy settings to the browser instance created by webdriver.

Below is a code that works with Firefox.

#Firefox keeps proxy settings in profile.
profile = Selenium::WebDriver::Firefox::Profile.new
profile.proxy = Selenium::WebDriver::Proxy.new( :http => "192.168.1.1:3128")
driver = Selenium::WebDriver.for :firefox, :profile => profile

driver.navigate.to "http://google.com"
puts driver.title
driver.quit

Answer 2

require 'rubygems'
require 'selenium-webdriver'
ENV['NO_PROXY']="127.0.0.1"
driver = Selenium::WebDriver.for :firefox
driver.get "http://google.com"

Answer 3

You probably have HTTP_PROXY (or http_proxy) set in your environment. The next release of selenium-webdriver (2.25) will also honor NO_PROXY/no_proxy (which you can then set to NO_PROXY=127.0.0.1). Until then you can remove the proxy from the Ruby environment before launching the browser:

ENV['HTTP_PROXY'] = ENV['http_proxy'] = nil
driver = Selenium::WebDriver.for :firefox

If you need the proxy configured for Firefox to communicate with the outside world, you could try something like this:

proxy = Selenium::WebDriver::Proxy.new(:http => ENV['HTTP_PROXY'] || ENV['http_proxy'])
ENV['HTTP_PROXY'] = ENV['http_proxy'] = nil
driver = Selenium::WebDriver.for :firefox, :proxy => proxy
