1338780 - WebExtensions must contain API for file system IO

Status: RESOLVED DUPLICATE of bug 1246236

(WebExtensions :: General, defect)

Description

[fdsc]

User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:51.0) Gecko/20100101 Firefox/51.0
Build ID: 20170125094131

Steps to reproduce:

The access to the file system is extremely important for debugging release versions of add-ons or distribute add-ons settings with the test addons.


Actual results:

The error message (in addition) from users could previously be accompanied by the installation of a test version of add-ons on their browsers with the same addon id and settings. When this extension was completely identical to the behavior when starting the browser (which not provides about:debugging).

Now its prevents the need for using signature add-ons.
So looking for other ways to debug.


Expected results:

USE CASE 1
1. The user should be able to provide detailed logs if he gets an error and developer cannot be repeated.
2. A developer wants get full user setting the additions. It is easiest to implement if it's possible to export the settings to the file.

USE CASE 2
It is possible to transfer add-on settings between different versions of the add-on or between different user profiles (to set up similar profiles).
