Modern WebKit / Blink based browsers can natively view PDF documents using a built-in PDF viewer.

Is is possible to control the PDF viewer, for example to open a document on a particular page or customize the PDF viewer toolbar by adding parameters to the document url?

For example, something similar to .pdf?page=4 .

Most answers from the web apply to ancient forms of PDF viewing, using external libraries, that are not longer applicable to modern WebKit browsers.
