Comment:

 Seems we need to flip
 `privacy.resistFingerprinting.autoDeclineNoUserInputCanvasPrompts` to
 `false` here as well, until the Mozilla bug gets fixed. I did that in
 `bug_27543` (https://gitweb.torproject.org/user/gk/tor-
 browser.git/commit/?h=bug_27543&id=ce60de442f949393b7f24acd153f82a57d78fe0e)
 in my public `tor-browser` repository. Please review.
