Man, that always sucks. Couldn't you have just done ctrl+shift+t and reload the tab? I think the website caches things like that.
I got super paranoid a while back and went on an internet privacy streak, installing (2) separate proxies (yes, I can't stream videos) and a shitton of anti-tracking plug-ins. Along the way, my browser stopped caching anything, so I can't play flash games over different periods of time. Or recover closed tabs. :(
On the plus side, there is 0% chance of anyone finding my browser history, so it's a net win.
Besides, I remembered most of it, so I'm finishing it up now.
Three cheers for government mandated holidays
