I am not sure but I think this issue has something to do with driver letter of my USB stick. It is H: on my home computer and F: on the one at work. The problem is; Firefox shows only the files I browse at home in the History. The files I browse at work do not ever go to History. Back - Forward buttons work but it adds nothing to History.
It works for me. You're using the latest version of Firefox do you?
