1404727 - Script modules don't work in extension popups

Status: RESOLVED DUPLICATE of bug 1371551

(WebExtensions :: General, defect, P5)

Description

[jakob.linskeseder]

User Agent: Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/62.0.3202.29 Safari/537.36

Steps to reproduce:

1. Set `dom.moduleScripts.enabled` to `true`.
2. Load extension (see https://github.com/jaylinski/webextension-module-test) and click on the browser-action button.


Actual results:

No console output is shown in the debug window (Console tab).


Expected results:

In the deubg window, the console should list the following output:
```
main            main.js:3:1
module a     a.js:4:5
module b     b.js:2:5
``` 

There is a similar bug in Chrome: https://bugs.chromium.org/p/chromium/issues/detail?id=769012

I'm using Firefox Developer Edition 57.0b3 (64-bit) on Ubuntu 16.04 LTS.

If the `popup.html` file is opened directly in the browser, everything works as expected.

Hi, same problem here: if a document on the moz-extension:// protocol includes a local module script, the local imports won't be loaded and the script will not execute.
The console reports

Security Error: Content at moz-extension://extension-id/page.html may not load or link to file:///path/on/local/filesystem/of/the/imported/script.

The file: path is shown if the extension is installed temporarily (via the about:debugging page). If the extension is properly installed a jar:file: URL is shown instead.

If I put the full moz-extension:// URL in the import statement the script is loaded and executed.
