Chrome backups all your browsing history which can be seen by using Ctrl + H. If you accidentally closed a tab and wanted to see it again use Ctrl + Shift + T to open it in a new tab. Holding Ctrl + Shift and then pressing T every time will open the last 10 closed tabs from your browsing history in a reverse order (latest opened tab will open first). Use Ctrl + Shift + Del to delete all your browsing history.
