844345 - MutationObserver not triggered from greasemonkey script with 20b1

Status: RESOLVED DUPLICATE of bug 844406

(Firefox :: Untriaged, defect)

Description

[bachus]

Attachment: example.user.js

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.7; rv:19.0) Gecko/20100101 Firefox/19.0
Build ID: 20130215130331

Steps to reproduce:

After upgrading to 20b1, the MutationObserver in my greasemonkey script no longer gets triggered. I use the script with the Scriptish addon. It works as expected after reverting to the prior beta version of Firefox. I have attached a simplified version of the script. I have another script that uses MutationObservers that still works, the only difference I can see offhand is that the attached script is using a document.querySelector as the target instead of just document as in the still-functional script.


Actual results:

The MutationObserver was not triggered.


Expected results:

The MutationObserver should have been triggered.
