Your cookies are saved as plain text files by both Firefox (Mozilla) and Internet Explorer. Each browser handles the files differently. Firefox maintains one file for all the cookies. The file is "cookies.txt".
Internet Explorer on the other hand keeps its cookies under either the Windows directory. There are a lot of files all with the ".txt" extension. For Windows they are in a directory under Windows called cookies. The files are named after the site that owns the cookie. For us that will be something like "<username>@granbyrotary.txt". It is possible that there may be more than one granbyrotary.txt in which case there is a number appended to the domain name like "<username>@granbyrotary.txt". The username will be your user name.
