[Bug 1426581] [NEW] with greasemonkey in firefox 36, "Error: Exposing privileged or cross-origin callable is prohibited"

[Steve Langasek]

Public bug reported:

I use a variety of greasemonkey scripts in firefox.  After accepting
today's update to firefox 36 from firefox 34, one of these scripts is
now failing with the following message on the browser console:

Error: Exposing privileged or cross-origin callable is prohibited

This appears to halt the script.

There is no other information given as to the cause of this error, and
the line number given is out of range for the source url.

Googling for this error message turns up some results, but none that
reference greasemonkey, and with nothing that would indicate how to fix
the problem.
