After clicking Clear List in Firefox downloads, Firefox will not show any downloads in the list how do I fix this?

Question

Firefox version 5
I had numerous items int the downloads window. I clicked clear list and it did. Now when I download something, it flashes for just a second in the downloads window and then disapears. The file is actually downloaded to the downloads folder.
