Add N Edit Cookies is a Firefox extension that integrates cookie manipulation in the web browser. A link to the cookie editor is added at the end of the tools menu. It will load in a separate window that acts independently meaning that it is possible to use Firefox with the Cookie Editor window being open.

The main window provides access to a filter that can be used to locate specific cookies. By default all cookies are shown in the list sorted by their site and cookie name. A click on a cookie will display extensive information including the cookie’s content, the path, host and expiration date.

A double-click on a cookie will load the editor with possibilities to edit the parameters of that cookie. It is possible to change the name, content, domain, path, connection and expiration date.

Another option would be to use the Cookie Editor to delete cookies. That’s simply a matter of selecting the cookies that should be deleted and pressing the Delete button.

The last option is the Add button which makes it possible to add a new cookie to the browser.
