How to install Adobe PDF Reader with Plug-in for Mozilla Firefox in Feisty Fawn

Adobe Acrobat was the first software to support Adobe Systems’ Portable Document Format (PDF). It is a family of software, some commercial and some free of charge. The Adobe Acrobat Reader program (now just called Adobe Reader) is available as a no-charge download from Adobe’s web site, and allows the viewing and printing of PDF files. It is a major component of the Adobe Engagement Platform, and is widely used as a way to present information with a fixed layout similar to a paper publication.

Several other PDF-editing programs allow some minimal editing and adding of features to documents, and come with other
modules including a printer driver to create PDF files.
