instantly opens up the PDF as a client inside Firefox, rather than give me a NoScript warning as previous.

Expected. The internal PDF reader is not a plugin, it's Firefox code and should't be blocked.
Otherwise, the internal HTML renderer -- which theoretically less safe because is written in C++, rather than JavaScript like PDF.js -- should be blocked as well.

If it really concerns you, then you can switch it off and use an external reader, like Tom T does. In your Firefox preferences, go to the Applications tab and change PDFs to Always Ask, instead of opening in Firefox.

Personally I think that a JavaScript-based renderer is inherently safer than anything written in native code - especially Adobe Reader - but that's just my own view. How you view PDFs is your choice .

Thank you for the reply.

I missed the upgrade in 19 that made the PDF code native, as previous versions of FF with NoScript did indeed block PDF links.

Thanks for the heads-up, I will probably will indeed make the configuration change.
