Whe I launch Chrome it shows a number in a square box on the toolbar. Touching this shows every web page I have ever opened!! It doesn't clear after a session, which I would expect it to do. Yes, I can go into settings and clear browsing history but can I stop it from keeping these pages cached in the first place? Or at least have it clear after a session. It seems utterly pointless to hold a cached page that I once visited 6 months ago!
