What kind of PDF tool do you want to use? The integrated PDF viewer "pdf.js" is quite good, but there certainly are browser plug-ins from third-party providers. – David Foerster Dec 5 '13 at 16:48

Try to download "adobe reader" or "viewPDF "from ubuntu software center.

I don't think this is an answer to the underlying problem, because the PDF viewer inside the browser has been working at an earlier time. – David Foerster Dec 5 '13 at 16:49
