Cookie Editor by Leonardo

Cookie Editor allows users to add, edit, or remove desired cookies on any website.

The interface for this addon can be opened in toolbar popup, a new tab, or a stand-alone window. Simply right-click on the toolbar button to choose the desired context. Once the UI is open, you will see all the available cookies for the active tab. Within the cookie table, you can see, domain, name, value, and other properties for each cookie item. Edit an item by clicking on the - pencil icon - next to it (left side). Moreover, items can be removed by marking the checkbox and then clicking on the - Remove - button at the top. In the top toolbar, there is a plus button that can be used to add a new cookie item for the current URL (or tab). Next is the trash icon which is for deleting all cookie items.
