What makes a file open automatically after download? I'm trying to stop it. I don't know whether Firefox or Sumatra controls this.

When I downloaded a .pdf file, it opens automatically after download. I want to put it back to where I have to click on it in the download window in order to open it.

This happens with every .pdf file I download.

I am using Sumatra 1.5.1 to view pdf files.
