PDFs from lumileds.com do not load with PDF.js. Part of the background loads, then only the spinner continues while using 100% CPU. 

An example pdf is http://www.lumileds.com/uploads/17/DS61-pdf 

This behaviour occurs with both the release version of pdf.js in firefox 41.0.2 and the latest .xpi downloaded from this github page.
