 I don't think so. The code that generates the error in my bug description
 is https://gitweb.torproject.org/tor-
 browser.git/tree/browser/extensions/pdfjs/content/web/viewer.js?h=tor-
 browser-31.6.0esr-4.5-1#n536. And its effect is that you can't download
 pdf files if you are clicking on the download symbol in the pdf viewer. It
 seems I should have made the latter clearer (I assumed everyone is
 downloading pdf files this way, actually :) ).
