Firefox is opening the PDF within the browser after generating the file. I am using C# and in the response header I use application/octet-stream and I am using attachment. Thank you,

Hi alanderos, The preference is stored in the Firefox profile. It can be changed in the Applications section of the Preferences menu. As for programmatically, I might suggest trying stackoverflow: *Where to go for developer support

What happens when you click this link:

http://www.jeffersonscher.com/res/getpdf.php?f=Mixed_Content_Blocking.pdf

That is served with:

Content-Type: application/pdf Content-Disposition: attachment; filename=Mixed_Content_Blocking.pdf

See: https://support.mozilla.org/questions/971296#answer-479623

Oops, I don't know anything about C#. Stack Overflow or Microsoft's forums would be a good choice.

What does Tools > Page Info > General show when this file is opened in a tab?

When the server sends a file as application/octet-stream then this should make Firefox show the download dialog.
