The built-in PDF viewer based on this plug-in is every bit as bad as these other reviewers have said. It displays files inaccurately, is wildly off at navigating to bookmarked pages when the bookmark is selected, etc. I'm astounded that in the latest updates to Firefox (v19), that Mozilla has made this completely substandard viewer the default.The good news: there's a way out.
