1269330 - chrome and browser namespaces are not injected into frames inside the background page

Status: RESOLVED DUPLICATE of bug 1258347

(WebExtensions :: Untriaged, defect)

Description

[Wladimir Palant]

Attachment: Minimal test extension

Steps to reproduce:

1. Download attached extension.
2. Go to about:config and set xpinstall.signatures.required to false.
3. Open Add-ons Manager and install the extension from file.
4. Press Ctrl-Shift-J (Cmd-Shift-J on OS X) to open the Browser Console.

Expected results:

The extension reports ["object", "object", "object", "object"] to the console - the first two values represent the chrome/browser namespaces inside a frame which has been added to the background page, the second two chrome/browser namespaces inside the background page itself.

Actual results:

The extension reports ["undefined", "undefined", "object", "object"] to the console - neither chrome nor browser namespace is defined inside a frame which has been added to the background page. This is different from Chrome's behavior, there the namespaces seem to be injected based on content location, not based on what is loading the page.
