Disable Firefox Built in PDF Viewer and get your power back
Why do these fucks at Firefox implement shit that without asking permission first. New in Firefox 19, a built-in pdf viewer that makes me wretch like watching the bad old win32 Adobe pdf plugin. Worst of all it is selected to be on by default!
Heres how to get ones freedom of choice back.
Navigate to Edit -> Preferences -> Applications and search for 'pdf', Set it to 'Always Ask'.
