I have Firefox v8. When I try to open a PDF file, all I get is a solid black box.

When I try to view a PDF file, at the start, I get a transparent box and as soon as I expanded it, it turns into a solid black rectangle. I wonder if there are any add-on which will fix this problem. If I use IE, I have no problem.

You have two PDF plugins installed for Firefox.

  1. Nitro PDF plugin for Firefox and Netscape
  2. Adobe PDF plugin for Firefox and Netscape '9.4.5.

Try disabling one that is not used by Firefox and make sure that download Action matches the plugin that you want to use Firefox.
