Reading the browser proxy settings in WebExtensions

[smellyfinger]

I used to be able to do it in my AddonSDK addon. Something like that:

Code: Select all

var prefs = require("sdk/preferences/service");
var currentProxy = prefs.get("network.proxy.http");

Now I can't find a way to do that in WebExtensions. Is there a lower-level, maybe Firefox-specific Api that can do this for me?
