Comment (by gacar):

 I just uploaded a new patch. This should allow chrome scripts and PDF.js
 to access canvas without the prompt.

 I built and manually tested patched Tor Browser on a handful of canvas
 enabled sites, it worked as expected.

 The only URL to be whitelisted for PDF.js turns out to be
 `resource://pdf.js/build/pdf.js`. There is a second script
 (`pdf.worker.js`), but it never shows up as a caller, probably because
 [https://github.com/mozilla/pdf.js/#building-pdfjs it's loaded by the
 first one].

 Let me know if anything is wrong with the patch.
