Some of the font rendering is broken in a great deal of newer PDFs. Is it possible that this matter was inherited from an older version of PDF.js? I'd like to rate higher, but that particular issue is significantly hindering. Edit: Rob Wu has reached out to me regarding my concern; he's advised that he'll be working on the matter when he has a moment. Other than the one issue I'd had, this is the best option for Chrome available.
