Don't like the new pdf.js Viewer. How can I disable it and restore Acrobat Reader as my favorite plugin?

I don't really like the look-and-feel of the new pdf.js Viewer. On my machine (6 yr old HP running Windows XP with sp 3) it displays more slowly than Acrobat Reader, and I was perfectly happy with the Acrobat Reader plugin. Frankly, I want to disable pdf.js, but have not been able to find a way to do it. It does not appear anywhere that I could find the Add-ons Manager. I don't want to be forced to use a feature that seems to be a detriment to performance, at least for me. Mozilla, please review this!

You can set the pref pdfjs.disabled true on the topic: config page to disable the build-in the PDF Viewer and use the Adobe Reader software instead.
