title: Firefox tabs - disable auto reload page on focus tab
body: <p>I prefere the <strong>keyboard</strong> for surfing in Firefox 20.0 and I use Shift + Page Up (Shift + Page down) to switch between tabs. In my preferences I have "When Firefox start: open the tabs from last session".</p>
  
  <p>Example: I start the browser, it automatically restore tabs 1, 2, 3,..., 20. from the last session. It's ok. It doesn't automatically refresh all tabs content - it's also ok, because I have setted up "don't restore tab until is selected". </p>
  
  <p><strong>But:</strong> If I try to move from tab 1 to tab 10, I have to go over tabs 2, 3, 4, 5, 6, 7, 8, 9 - and here is the problem, because it starts to refresh the tab 2 - 9 content and I don't need it now, it takes a long time, especially if I have more tabs open. </p>
  
  <p>I tried to set in about:config </p>
  
  <pre><code>accessibility.blockautorefresh = true, 
  </code></pre>
  
  <p>but it doesn't work. </p>
  
  <p><strong>Generally:</strong> I need to disable all auto refreshing web pages (tab content), so it will load only the tab and if I will decide to load its content, I'll press F5, Ctrl + F5, or something like that.  </p>
  
  <p>Do you have any idea, how to fix that? Sorry for my English.</p>
  
  <p>Thanks for any help.</p>
