Managed storage seems does not work in W10 64bit...

[marcogaio]

I've setup following the doc a simple .json file:

{
  "name": "[email protected]",
  "description": "Managed Storage for IE View WE",
  "type": "storage",
  "data": {
    "forceielist": "https://sissi.*.lnf.it/*",
    "disableForce": false,
  }
}

then setup the default value for keys HKLM\SOFTWARE\Mozilla\ManagedStorage\[email protected] to %ProgramFiles%\Mozilla Firefox\browser\defaults\[email protected], and clearly copying the file in that position.

But if i run even a fresh profile of FF the forceielist get not setted, and in console i got:

Successfully compiled asm.js code (total compilation time 1ms) background.js
Unchecked lastError value: Error: Managed storage manifest not found settings.js:20

all seems to me unrelated.

What i'm doing wrong?! Thanks.
