Is there a way to listen to event when a cookie is changed in a Firefox Extension
提问by ivanceras
I am trying to build a firefox extension which listens to events when a cookie is changed by any domain from any page and handle it accordingly. Is there an easy way to do this in javascript?

You can listen to the cookie-changedtopic with the observer service.
您可以使用观察者服务收听cookie 更改的主题。
