Run Ccleaner Automatically When Browser Closes

Hi, I run Ccleaner everytime I close my browser, as do many other people I know.

It would be good to have an option to do this automatically, and with whatever browser you are using :)

It would be useful to some people. Been suggested a few times so i guess the devs have seen it.

One question though, if you want history to be cleared after every session. Why not use FF private browsing?
