Cookie Editor

Cookie Editor is an application that helps you to manage client cookies.
Cookie Editor allows you to maintain the level of your privacy by allowing you to see, edit, block or delete any unwanted cookies.

It also allows viewing and deleting browsing history. It searches your computer for cookies then displays them in easy grid-like format. You can examine content of any cookie or delete it.
Users of Mozilla, Netscape and IE 6.0 or newer can also block or allow cookies from specified domains.
For advanced users, you can also edit the contents of cookies. So, for example, if you want to change your zip code for movies.yahoo.com, or push up the expiration date of a wanted cookie, you could do so without even opening your browser!
Supported Browsers: Internet Explorer, FireFox, Netscape, Mozilla.
