PDF issues                 

                         

Many recent browser versions include their own, native PDF plug-ins that automatically replace the Acrobat and Reader plug-in from Adobe. Installing Firefox 19 or later, for instance, can result in your Adobe plug-in being disabled and replaced. Browser plug-ins typically do not support all PDF capabilities or offer comparable features. If you experience the following problems, you may need to revert to the Adobe plug-in:

  • Parts of a PDF don’t display
  • Poor performance or image quality
  • Large files sizes when printing to PDF
  • 3D models don't render
  • Embedded SWF files don't play
