How to prevent MP4 files from downloading on Linux & Firefox with JWPlayer

I have JWPlayer running on my system, with no issues -except one. For some reason, on Firefox on a Linux CentOS machine, JWPlayer will not automatically play the MP4 video. I will give the user an option to "Open with" (Media Player/Default) or "Save File".

How do I prevent users from being able to download the MP4 file? My JWPlayer setup is set up for streaming & HTML5 fallback, as shown below. These are served from Amazon CloudFront.

jwplayer('container').setup({
playlist: [{
ga: { },
title: '$title',
image: 'XXX.png',
sources: [{
file: '$cf_stream_uri$stream_url'
},{
file: '$down_url'
}]
}],
height: 600,
primary: 'flash',
width: 800
});";
