This add-on provides an extra button on your navigation toolbar that allows you to allow websites to set cookies on your computer. Cookie-permissions can be added on a sub domain or domain level (e.g. just for mail.google.com or all google.com subdomains). Cookies from domains that are not currently allowed to set cookies (i.e. cookies that are actively denied, or not explicitly allowed if cookies are blocked globally) will be deleted on closing the browser. This behavior can be changed in the add-on's options.
This add-on also allows the user to allow a website for the current session. Session permissions will be deleted when the browser is closed. The add-on also provides easy access to global cookie settings, cookie permissions and the browser's cookie viewer.
