Setting preferences to bypass the new PDF viewer

My Firefox preferences for all types of PDFs are set to "always ask," which is what I want. What happens instead is that they automatically open (very slowly) in the new Firefox PDF viewer. I want to have what I used to have: the opportunity to decide whether to open or save, and if I choose open, have that happen in Acrobat or Reader. I realize that I can (at least theoretically) set the preferences to automatically open in Acrobat, but that's not what I want. Is there any way to set preferences so I still get the functionality I had before the upgrade to Firefox 19? (I'm using Firefox 19.0.2 on a Mac.) Thank you.

please also make sure that the default action for the entry named portable document format (pdf) in the preferences > applications tab is set to always ask. then it should work as intended...

(the screenshot is taken on windows but it will look similar on your system).

hello, enter about:config into the firefox location bar (confirm the info message in case it shows up) & search for the preference named pdfjs.disabled. double-click it and change its value to true.

That's helpful, but not exactly what I was looking for. This makes the PDF automatically download, which is a definite improvement, but ideally I'd like to have the old open-or-download option back so I could decide on a case-by-case basis (and then if I choose "open," get it to open in Acrobat). Or, it would also help to know for sure that that's no longer an option.

Still, huge improvement (and I can definitely live with this if it turns out there's no way to do the thing I'm describing) -- thank you very much.
