It seems Firefox has downloaded a document or a picture to the desktop. On the top bar, there is an icon - small downward pointing arrow over a bar. When I click on that it brings up a history of my downloads (docs, pics, pdfs, etc.....NOT software downloads). There appears to be many previous downloads in this window, they appear to be done, but NOT completed and are just hanging there in never never land. By clicking on the bottom item (3 other items), it opens a window called Library. The second options to the left is downloads. The instructions tell you to click on the "Clear Downloads" on the upper bar (Next to Organize) and this will clear out all the downloads. This Clear Downloads is, however, grayed-out. There seems to be no other ways to clear this list. Any help would be appreciated....

Thanks
