title: watir open each link of a page
body: <p>I need to scrape some info on a website that has a table where each row contains a link.</p>
  
  <p>I want watir to click each link in that table, grab some info from the generated page and go back to the previous page.</p>
  
  <pre><code>t = browser.table(:class =&gt; "tblElencoProdotti")
  
  t.links(:class =&gt; "TXT10b").each do |l|
    l.click
    #do some stuff
    browser.back
  end
  </code></pre>
  
  <p>Unfortunately the back action brings me to a "Document Expired This document is no longer available" error.</p>
  
  <p>This works if I manually do the operation on my default ff session and hit the back arrow, but somehow it does not work if I do that in the watir opened window.</p>
