"policies": {
   "ExtensionSettings": {
     "*": {
       "blocked_permissions": ["tabs"]
     }
   }
 }

How can I apply a policy based on "blocked_permissions". I've read Chrome documentation but I guess Firefox does not support this parameter. Right? If so, is there any way to request this feature? I need a policy like { "policies": { "ExtensionSettings": { "*": { "blocked_permissions": ["tabs"] } } } }
