Doesn't Open PDF Rated 1 out of 5 stars

This extension doesn't seem to work. With the Adobe Reader plugin disabled and this add-on enabled, PDFs are directed to be downloaded. There are no buttons or menus associated with this add-on that get added to the browser. Had to enabled Adobe to view the PDFs.

Other PDF add-ons have other issues, but at least they all opened PDFs. This one is worthless. (Win 7/ 64 bit)

This review is for a previous version of the add-on (0.16).
