Firecookie is an awesome extension for Firebug I just recently discovered. It makes it possible to view and manage cookies in your browser. Unlike the other cookie managers and views that are avaiable as extensions to Firefox, this is an exclusive plug in for Firebug. This keeps things clean and simple in my opinion since Firebug is running 24/7 anyway.

After Firecookie is installed you will see a new tab within Firebug’s bar called Cookies.  Clicking this tab will then display all cookies associated with the current domain. Each item lists the basic information about that cookies. So things like name, value,path, expire date and domain.

But where Firecookie really gets useful is when you want to see when something happens to a cookie in real time. Using the existing Console tab in Firebug, Firecookie creates a log entry every time a cookie is created, changed, deleted or rejected.
