Steps to reproduce:

As specified here: https://developer.mozilla.org/en-US/docs/Mozilla/Tech/Xray_vision
I have used Components.utils.waiveXrays(window.wrappedJSObject.GlobalObject).Foo() in a content script. Foo is a function added via prototyping.


Actual results:

TypeError: Components.utils is undefined.


Expected results:

I have expected to see the unwrapped object with the prototyped properties available.

:mixedpuppy, do you happen to know if this is applicable to webextensions?

Comment 2

Components is not available to extensions, the docs should be updated.

Sorry if this is off-topic, but is there another way for extensions to access prototyped page script object fields then?

I've added a note to the cited doc to say this is not available to webext, but is there something else that needs to be updated, to your knowledge?
