Add N Edit Cookies is another must have Firefox extension that makes it easy to add or edit cookies from within Firefox. Cookies are linked to specific sites which create them on the local system during the connection process. This can happen as soon as you visit the site, log in to it or change a preference that it makes available to you.

The publisher of the site selects what information are stored in cookies, which often is not overly interesting. Sometimes though you may want to find out what a publisher saves in those cookies, and while you can check cookies manually on your system, you'd spend quite some time doing so.

This Firefox extension will list all cookies currently saved by Firefox to provide you with details about individual cookies once you select them from the list. The list itself will keep you informed about the website that created the cookie and the name of the cookie. There is additional information on this main screen like the content of the cookie, which is most likely encrypted, or the expiration date of the cookie.

  1. Name - The name of the cookie
  2. Content - Its content
  3. Host - From where it came.
  4. Expires - When the cookie expires naturally.

The edit menu displays all the information already listed in the main window and gives you the option to alter the saved values. You could make cookies expire early for instance or try advanced methods of altering cookies that might get you into restricted areas of the website that you are visiting.

Update: The Firefox extension is no longer compatible with recent versions of the web browser. An alternative is FlashCookiesView for the Windows operating system. While it does not provide you with the means to edit the cookies, it displays all the cookies and their contents in its program interface.
