Selective Cookie Delete is a cookie manager add-on for Firefox that makes it easy to manage and automatically delete the cookies you don't need. The app offers two working modes. You can use a Blacklist if you want to keep all cookies, except those from sites that you specify, or you can use a Whitelist which will delete all cookies, except those from specific sites.For most users, the Whitelist mode will probably be the most efficient approach. It allows you to select the cookies that are important to you (e.g. your bank, your newspaper etc.) and all other cookies will be deleted. If you configure the app to delete cookies automatically, you'll never have to worry about useless tracking cookies accumulating in your browser.You can choose to delete cookies manually by using the provided toolbar button and you can also have the program delete your cookies each time you close your browser.
