Solve PDF issues by reconfiguring your browser to work with Acrobat or Reader plug-in.
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
Solution: Revert to Adobe PDF plug-in

Manually change your browser preferences so that it uses the Acrobat or Reader PDF viewer.
