If you don't have a file manager on your system chances are you can figure out where downloads are going to.

Well, I manage it sometimes, but I then I forget how I did it. I think the way to do it, is to try to download something with ff again, but stop at the file chooser dialog to figure out where it points to.

You can configure FF that it will ask you each time, where you want to save the file.
