(Director of Strategy for Mozilla Research here.) pdf.js was the brainchild of Andreas Gal, now our CTO but at the time a cofounder of Mozilla Research along with Brendan Eich and me. That project started briefly in Research but was shepherded to product pretty quickly. Shumway is a separate project but similar in spirit. It's not a converter per se, but rather an emulator including a full ActionScript Bytecode (ABC) JIT, implemented in pure JavaScript. Right now we are interested in getting Shumway to the point where it can be used in Firefox as an alternative to the native Flash plugin for certain kinds of web Flash content, to provide better security, stability, and performance. Over time as Shumway matures the ultimate goal would be to eliminate the need for the Flash plugin entirely, but we'll walk before we run. But Shumway is usable as a standalone project as well, and others have begun taking notice. For example, Prezi has invested in Shumway as a library for rendering vector graphics: https://medium.com/prezi-engineering/how-and-why-prezi-turned-to-javascript-56e0ca57d135 https://medium.com/prezi-engineering/how-and-why-prezi-turne...
