Before validating, Thunderbird normalizes platform input in PolicySchemaValidator.sys.mjs: a value delivered as a JSON string is parsed where contentMediaType is application/json, and 0/1 integers become booleans. After validation, strings with format uri become URL objects, and a list entry that fails validation is dropped and logged rather than discarding the whole policy.",
