Mozilla Puts Native PDF Viewer in Firefox 19
The Portable Document Format is one of the more ubiquitous document types both on the Web and on personal devices, and can be used for distributing manuals, brochures, and most other formatted documents. However, until now Firefox, one of the more popular Web browsers, in part due to its availability on OS X, Windows, and Linux, has not had a built-in PDF reader. Instead, to open PDFs it's been necessary to either install a browser plug-in or download the PDFs and open them in a managing program like Apple's Preview.
