how do i create a file that sets all clients to "Use Adobe Acrobat (In Firefox)"
The built in firefox PDF viewer is causing certain PDFs to print out solid black pages. I have found how I can add // Disables built in PDF viewer defaultPref("pdfjs.disabled",true); to mozilla.cfg to disable the built in PDF viewer for all users. I am also needing to find a way to set all the clients to "Use Adobe Acrobat (In Firefox)" as the default action for all users when clicking a PDF using a deployed file. I have found multiple articles talking about going to Options--Applications, and then setting the default PDF action, but with 3300 clients that is not a viable solution. If there is a way to edit mozilla.cfg or create a .js file that will set the default PDF action, that would be optimal. Then I could just bundle the file with my current install package and deploy it to all machines remotely with the next update. Any help is greatly appreciated.

Hi farleydw, This was a major issue that was updated. The only difference I see is that they are white: See the Release Notes
To change the default pdf viewer in a mozilla.cfg file I will borrow a response from the top contributor cor-el: "ou can use a mozilla.cfg file in the Firefox program folder to specify new (default) values and possibly lock prefs.
Place a local-settings.js file in the defaults\pref folder where also the channel-prefs.js file is located to specify using mozilla.cfg.
pref("general.config.filename", "mozilla.cfg");
These functions can be used in the mozilla.cfg file:
defaultPref(); // set new default value pref(); // set pref, but allow changes in current session lockPref(); // lock pref, disallow changes
