Cookies are small pieces of textual information stored by webpages on your computer. Their many uses include remembering login information and preserving the contents of your basket on shopping sites. For more information about the concept, see the Wikipedia article.

Cookie permissions

In Firefox you may choose to accept all cookies that websites wish to set; or you may prefer to accept only those which come directly from websites you visit but deny third-party cookies which are often set by other companies who advertise on those sites.

Exceptions list

As well as the basic permissions above, you may also make blacklists and whitelists using the Exceptions list. The settings in this list override your basic cookie settings, so that you can have stronger control over individual sites that you have manually added to the list. You can choose to allow an individual site to set cookies, allow it to set only cookies which are deleted once you have closed Firefox, or deny it from setting cookies at all.

Where are cookies stored

Cookie information is stored in two files: cookies.txt and hostperm.1. (Older versions used cookperm.txt instead of hostperm.1.) Both of these files are located in your profile folder.

File Description
cookies.txt Holds all of your cookies, including login information, session data, and preferences.
cookperm.txt
hostperm.1
Holds preferences about which sites you allow or prohibit to set cookies, to display images, to open popup windows and to initiate extensions installation.
