Do you have multiple versions of Adobe Acrobat Reader installed on that PC? Or maybe Acrobat Reader and the full Reader program, but differing versions?

You can check the "C:\Program Files\Mozilla Firefox\plugins" folder to see if there is a nppfd32.dll file in that folder.
You can see the installed plugins on the about:plugins page. If you set the pref plugin.expose_full_path to true on the about:config page then you see the full path of plugins on the about:plugins page. It is best not to leave that pref set to true as it exposes that full path to web servers, so reset that pref to false after you are done with the about:plugins page.
You can open about:plugins and about:config via the location bar, like you open a website (about: is a special protocol to access some build-in pages). If you get a warning when opening the about:config page then you can confirm that you want to continue.
