Automatic download of PDF files

I am trying to use DownloadStudio with Firefox 3.6.16. I would like for DownloadStudio to download pdf files by default when I click on the link to the pdf file. That, however, is not what happens. I know that I can right click on the link to the pdf file and have Download Studio download it that way, but what I was hoping was that just by clicking on the link to the pdf file, it would download it automatically. The download manager I have been using has this feature, so hopefully I can do this with Download Studio. Can someone tell me how to make Download Studio do this?

Thank you in advance for your assistance.

It is not currently possible to make DownloadStudio automatically download pdf files, it might be possible to include this functionality in a future version of DownloadStudio.
