Mozilla’s PDF.js is now available for upcoming Opera 15+ browser as a standalone extension. PDF.js is an open source PDF reader built using open standard technologies.
After shipping the Firefox 18 as regular stable version, Mozilla has released the next beta version, Firefox 19, for desktop and Android platforms.
The PDF.js has not enabled by default in Firefox 18, and Mozilla is now targeting it for the Firefox 19.
Firefox 14 gets an awesome feature: an integrated PDF reader powered by PDF.js. This means that the users can open and view PDF files in the Firefox without any third-party tool like Adobe Reader or Foxit Reader plug-ins.
