title: How PREF cookie (google.com) appears in firefox?
body: <p>Remove all the history in Firefox (delete all cookies), disable all add-ons and plugins, then restart Firefox. <em>Do not go to any site</em> and wait for about 10-15 min. Go to <em>Options->...->Show cookies</em>. You will see cookie named <strong>PREF</strong> with <em>google.com</em> domain.<br>
  1) Can somebody explain how and why this cookie appears?<br>
  2) How to get rid of this?</p>
  
  <p>p.s I don't have any google desktop application installed. Firefox google search bar is removed too.</p>
