2. The issue is not reproducible on Firefox 28, so it's a recent regression. Please see the regression range below:

Seems to be regressed by bug 965861.
Mac OSX Preview matches PDF.js output. Looks like something wrong with the PDF.js since some viewers cannot handle it well too. What Adobe Reader displays?

Correction, Looks like something wrong with the PDF document
Yury, the pdf is displayed fine in Firefox 28. Please see the attachment, the upper side is the view from Chrome.

I'm not saying we are not going to closing it as won't fix. I'm just saying that it can be a problem with the PDF (attaching Preview screenshot). The https://github.com/mozilla/pdf.js/pull/4161 fixes missing functionality, but this particular PDF expresses some weird corner case or contains incorrect data.
