It seems like every time I open a PDF or something from Firefox and it opens
in Preview, the file is saved to my desktop! That seem so lame. I can't
see any place in either Preview or Firefox to set this. My "downloads"
directory is set to a completely different spot in Firefox, so when I
actually "download" a file it goes to the right place, but anything that
"opens" a file into Preview goes to the desktop - it's annoying

Anyone know how to prevent this??
