When Firefox creates history entries of pages that are already registered in the history, it overrides the older ones and keeps the new ones; however, the old data entries still exist as history.dat / index.dat (whatever FF uses) and i would like to know if there's a way to 'refresh' the history so that it shows all of the entries. What i mean is, is there a way to re-enter the old history entries which have been booted out of the "show all history" panel? For example, if i go to www.youtube.com today, and then tomorrow go to it again. The old entry will be deleted and the new one will be kept. But the old entry still exists on my computer, so is there a way to re-enter it?
