Comment (by mcs):

 Replying to [comment:6 gk]:
 > gacar: No, that does not fix the bug. The problem is not the scheme of
 the document but rather whether the script that uses the canvas is a
 content or a chrome script. The patch we have assumes there are only
 content scripts doing that and thus just checks whether the
 document/website loaded is a chrome one or not.

 I have not had a chance to debug this problem yet, but the intent of the
 patch was to check the security characteristics of the running script.
 Either the check is incorrect or PDF.js and the developer tools inspector
 do not run with system privileges.
