在pcflank上测firefox有两项没过

quick test
Browser privacy check
The test checked if your web browser reveals any private information while you visit Web sites. Usually such information is: the last site visited, your locale and who your Internet Service Provider is.

browser test
Referrer check
Danger!  While visiting web sites your browser reveals private information (called 'referrer') about previous sites you have visited.

请达人说说有没有办法解决，比如用扩展之类的
