Pdf is quite a standard. One might wonder what it cannot do. One could call it evil.

Ah yes, a image within a PDF could definitely do this I suppose. I just thought it odd that the browser would leak this out. dnsmasq[3151]: query[A] pdf.js from 10.6.24.11 dnsmasq[3151]: query[AAAA] pdf.js from 10.6.24.11 dnsmasq[3151]: query[A] pdf.js from 10.6.24.11 dnsmasq[3151]: query[AAAA] pdf.js from 10.6.24.11 This could become a whole can of worms if a .js TLD ever makes it to the internet and registers this domain name. We see this from Ubuntu terminals running Mozilla Firefox 33.0 Best regards, Seth

Hi,
Whilst rummaging through some DNS (dnsmasq) logs I've noticed quite a decent amount of queries for pdf.js from what appear to be mozilla browsers.
Seems rather odd that it is performing DNS queries for a internal PDF viewer.
Has anyone else come across these lookups?
Kind regards,
Seth
