How do I access my private browsing history? I'm trying to recover some pages that I had open when my macbook (OSX 10.8.5) crashed.

Unfortunately I was using Opera (V30) in private browsing mode. 
I've tried looking at my DNS cache - but not exactly sure how to read it. (I can't see the URLs in the text)

I've also looked at my router logs but can only find info like this:

May 9 00:39:27&gt; PPPD Successfully Launched
May 9 00:39:32&gt; pppd 2.4.3 started by root, uid 0


Just to let you know - I'm not trying to snoop on anyone, really just want to recover the pages I had open!
Here is a quote from a Wikipedia:

Privacy mode


  Privacy mode or "private browsing" or "incognito mode" is a privacy feature in some web browsers to disable browsing history and
  the web cache. This allows a person to browse the Web without storing
  local data that could be retrieved at a later date. Privacy mode will
  also disable the storage of data in cookies and Flash cookies. This
  privacy protection is only on the local computing device as it is
  still possible to identify frequented websites by associating the IP
  address at the web server.


You may try to find logs from any routing, filtering or tracking hardware or software inside your network, or from your Internet provider.
