Developer fails to mention that all PDFs are created with a password required to edit - it's not on the Firefox page, it's not on their website, it's not mentioned in the add-on. This is utterly misleading, and is an obvious attempt to try and hook you into paying a fee to unlock them before you realize you have no choice to but pay to edit all the documents you just created. So not cool. Too bad, because if they had, I wouldn't feel upset and probably would have paid a fee if I'd known this was required. Now I just feel jerked around. Bad practice, PDF Mage, just bad practice.
