个性化推送如何兼顾隐私与便利，也许 Firefox + Pocket 的模式可行

服务端无差别推送每日主题列表，在客户端进行个性化筛选与展示，没有隐私数据被发送到服务端。

• If the “ Recommended by Pocket ” feature is enabled, Pocket will send a list of the best stories on the web to Firefox every day.
• With each story, Pocket also sends a list of related websites that, when visited, signal likely interest in the story.
• Your Firefox browser compares your browsing history with the list of related websites to sort and filter through each day ’ s stories and recommend the ones that are most likely to interest you.
• Important Note: Neither Mozilla nor Pocket receives a copy of your browser history. The entire process of sorting and filtering which stories you should see happens locally in your copy of Firefox.
