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> PPPD Successfully Launched May 9 00:39:32> 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!
