1473243 - Add the capability for about:config to export all preferences in readable format

Status: UNCONFIRMED

(Toolkit :: Preferences, enhancement, P5)

User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:52.0) Gecko/20100101 Firefox/52.0
Build ID: 20170921064520

Steps to reproduce:

I was not able to add an existing plugin in zul (https://addons.mozilla.org/en-US/firefox/addon/config-export/) allowing myself to export nearly all preferences as a CSV file. This is very useful, and have reduced a lot our delay to deploy new ESR releases when there are available. We do comparison between previous releases like change in defaults, new parameters, obsolete ones .... very useful


Actual results:

This module written in XUL/JS adding an export capability in about:config does not work anymore. Based on finding there is no equivalent capability in web extensions API and lot of talks about the fact there will not be such capabilities because of the "change capability" -> Security related


Expected results:

It is proposed to just add an export action in the about:config grid popup menu, allowing the export of all properties in an easy to read CSV format. NO security issue as not introducing import or setting options nor APIs
