How to Delete Cookies

Firefox 2.x

Sometimes Firefox will ask you if you want to accept a cookie. A cookie is a small amount of information that a site will save to a special file on your hard drive, then examine when you visit the site again (e.g. shopping cart information for an online business). They are usually harmless but they can present a privacy issue, since sites can use them to track what pages you visit and other personal details.  They also tend to cause problems with certain Content Management Systems (CMS) like Plone, etc...
