Mozilla Firefox cleaning

In my settings, it says that it will delete history, etc. of Firefox, but I have those boxes checked and have run cleaner and my history all still exists. Am I doing something wrong? Someone please help.

Have you created a Firefox profile in a non-default location?

Thanks for your reply. No. I have done the standard installation.

It usually works fine for me. There was a time, though, when a problem with Firefox caused duplicate cache folders to be generated, and these were not being cleaned out.. Even though I was clearing the cache after every browsing session, I found I had 4 cache folders, when there should never be more than one.

You should take a look in your Firefox Profile, see if you have extra history.dat files. If you don't know how to find the Profile folder, read this article:
