The "Open in PDF viewer" extension opens PDF files directly in your favorite external PDF viewer application. To use the extension, right-click on a PDF link and select the "Open in PDF viewer" item. The extension downloads the PDF file in your default downloads directory and then executes the external command to open the downloaded file with the default PDF viewer (e.g. Adobe Acrobat Reader or FoxIt PDF reader).

Note that to execute an OS-level command, you need to install a native client. Native client installation guide appears on the first usage.

It does work, however the inability to download the pdf to a temporary file and open it from there, the way Firefox can, makes this app unusable for me. If it would at least give the option to choose a download location I could set up my own temporary file and use Windows Task Manager to occasionally delete the file then maybe I could work with it, but it gives no other option other than your default downloads file, which I do not want filling up with a bunch of pdf's.

It copies the file into the user's downloads folder. The whole reason we need it is for users to edit PDFs and fill and sign forms. If they're editing a local copy, changes they make won't be copied up to the original location. This is not at all useful for us.
