Always - all cookies from websites other than the site you visit are allowed.With Firefox 22, a new option is introduced to block third-party cookies from web sites which you haven't explicitly visited before, thus making it harder to employ cross-site user tracking based on such cookies. Starting in Firefox 3, you can block third-party cookies in the user interface, by deselecting (clearing) the option, 'Accept third-party cookies'. You may choose to accept all cookies that websites wish to set or, in Firefox 3.0 and above, you may choose to accept or block third-party cookies that are often set by other companies who advertise on those sites.

You may have to choose 'Use custom settings for history' in the 'Firefox will:' drop-down menu to see more options. (In SeaMonkey 1.x and the earlier Mozilla Suite the Cookie Manager was a separate panel, accessible via 'Tools -> Cookie Manager -> Manage Stored Cookies' and the tabs were named 'Stored Cookies' and 'Cookie Sites'.)Ĭookie permissions are controlled in ' Tools -> Options -> Privacy'. You can open Data Manager from the button in Preferences 'Privacy & Security -> Cookies' described above and also from the menu item 'Tools -> Data Manager'. In SeaMonkey 2.x, the Data Manager lets you view or delete individual cookies for a site ('Cookies') tab and override basic cookie settings so that you can allow or block cookies for individual sites ('Permissions' tab). This has a button that opens the Data Manager to control cookie settings per-site. Ask for each cookie (you can limit these warnings by choosing 'except for session cookies').Accept for current session only (deletes the cookie the next time you exit your browser).If you allow cookies, you can also select the following retention preferences: You can choose to block all cookies, allow all cookies, or to allow cookies for the originating website only (thus blocking third-party cookies), In SeaMonkey 2.19 and later, third-party cookies can be restricted to allow cookies from previously visited websites only.

Overall cookie permissions are controlled in ' Edit -> Preferences -> Privacy & Security -> Cookies'.
