Firefox 3rdparty Policy support

[lomenzel]

Hey there,
does TST support configuration via the Firefox policies?

https://extensionworkshop.com/documentation/enterprise/enterprise-development/#how-to-add-policy

[piroor]

Yes, TST (and other my Firefox addons) supports configuring via GPO and policies.json.
Here is the complete list of configurable options:

      "Extensions": {

    }
  }
}

I recommend you to configure TST by hand and export all options, then copy exported data and paste it under policy.3rdparty.Extensions.treestyletab@piro.sakura.ne.jp. They are locked by default but you can allow users to change the option with setting "<name>:locked":false (so it means "changing the default value").
