title: Watir Webdriver Load Chrome Extension
body: <p>I'm trying to load a chrome extension with Watir, and I'm having issues.
  I found this related question: <a href="https://stackoverflow.com/questions/12586751/ability-to-launch-chrome-with-extensions-loaded-with-watir-webdriver">Ability to launch chrome with extensions loaded with watir-webdriver</a>.  However, I am still having the same issue after following that.</p>
  
  <pre><code>require 'rubygems'
  require 'watir-webdriver'
  require 'ruby-debug'
  require 'nokogiri'
  
  browser = Watir::Browser.new :chrome, :switches =&gt; %w[--load-extension=~/.config/google-chrome/Default/Extensions/anepbdekljkmmimmhbniglnnanmmkoja/0.1.12_0]
  
  sleep(10)
  browser.close
  </code></pre>
  
  <p>I also tried copying the extension from /Extensions to /Desktop and loading from there to no avail.</p>
  
  <p>The error I get is <code>Could not load extension from ... Manifest File Missing or Unreadable.</code>
  The Manifest file does indeed exist and seems to be a correct file in JSON format.</p>
  
  <p>Trying to load different extensions fails as well.</p>
