When I go to

http://www3.interscience.wiley.com/journal/118746902/abstract

I get an icon, and a successful download of bibiliographic
information, but ... instead of saving the associated PDF,
Firefox pops up the option box for opening or saving the
PDF. (I have "save associated PDF file" checked in preferences.)
Searched the forums but didn't see similar issues raised.
FF 3.0.3, Zotero 1.0.7 ...

thanks
