Mozilla published Firefox 19 Beta and one of the new features in this release is the inclusion of a built-in, secure PDF viewer that uses HTML5 and JavaScript.
For a number of years there have been several plugins for viewing PDF’s within Firefox. Many of these plugins come with proprietary closed source code that could potentially expose users to security vulnerabilities. PDF viewing plugins also come with extra code to do many things that Firefox already does well with no proprietary code, such as drawing images and text. These problems, and the desire to push the boundaries of the HTML5 platform, led Andreas Gal and Chris Jones to start a research project they named PDF.js. The project quickly picked up steam within Mozilla Labs, where it grew into a full-fledged PDF viewer.

Today, the PDF.js project clearly shows that HTML5 and JavaScript are now powerful enough to create applications that could previously have only been created as native applications. Not only do most PDF’s load and render quickly, they run securely and have an interface that feels at home in the browser. As an added benefit of using standard HTML5 API’s, the PDF viewer is capable of running on many platforms (PC’s, tablet, mobile) and even different browsers. Last, performance will only get better as JavaScript engines and rendering performance continue to improve in browsers.
