mozilla firefox addon settings - firefox

Question

I think there's a file where settings of every addon installed are stored. Where can I find it?
I need the name of the extensions, the version, the state(enabled,disabled,uninstalled) and the extensions ID.

All the information you seek is in $profD/extensions.json
E. g.
{
"schemaVersion": 17,
"addons": [
{
"id": "addon#example.org",
"syncGUID": "-3yoR7F-ml47",
"location": "app-profile",

},

"defaultLocale": {
"name": "My addon",
"description": "Addon description",

},
"visible": true,
"active": false,
"userDisabled": true,
"appDisabled": false,
"descriptor": "/home/user/.mozilla/firefox/w7svh0gr.ffnightly/extensions/addon#example.org",

"targetApplications": [

Don't need to find out the add-on files. Just use the AddonManager.jsm service:
const { Cu } = require("chrome");
let AddonManager = Cu.import("resource://gre/modules/AddonManager.jsm").AddonManager;
AddonManager.getAddonsByTypes(["extension"], function(addons) {
var addonData = [];
for (let i in addons) {
let cur = addons[i];
addonData.push({
id: cur.id.toString(),
name: cur.name,
version: cur.version,
active: cur.isActive
});
};
console.log(JSON.stringify(addonData, null, ' '));
});
For more detail on this just read these two docs.
