SecurityDevices section in org.mozilla.Firefox.json does not work

[rougegoat]

I've been testing all the configurable options in Firefox using manifests. I noticed the approach used here does not work. The code section reads:

"SecurityDevices":{ "type": "array", "title": "Security Devices", "description": "Install PKCS #11 modules.", "items": { "type": "object", "properties": { "key": {"type": "string", "title": "Device Name"}, "value": { "type": "string", "title": "Device", "default": "PATH_TO_LIBRARY_FOR_DEVICE" }, "propertyNames": {"type": "string"} } } },

This seems like it should work, but Firefox gives the error "Invalid parameters specified for SecurityDevices." if you use it. I'm guessing Firefox is looking specifically for an object and not for an array of objects and rejects it before parsing anything.
