Firefox Beta now includes a safer, more seamless cross-platform experience for viewing PDF documents. The PDF.js project 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 PDFs load and render quickly, they run securely and have an interface that feels at home in the browser. As an added benefit, the PDF viewer is capable of running on many platforms (PC’s, tablet, mobile) and even different browsers.”]
