最近想订阅一个RSS feed，然而由于权限设置，需要登录才能拿到内容，未登录的情况下feed url会报错。
Now I'd like to subscribe a private RSS feed, where login is necessary, you won't see anything from the feed url without login.
In such a situation Google Reader won't work, even if possible, I don't want to reveal my username/password to it.
After wasting several minutes in Googling, I came up with an idea, that to subscribe the feed using Firefox, as it's holding my Cookies.
Then of course I succeeded.
