CookieKillerCookieKiller
This is a small Firefox Extension that adds a sub-menu to the context menu and an icon in the status bar which allow the user to selectively kill (remove) cookies based on the domain that set them. The user may also remove all cookies for the current domain or all cookies that are present.
If you like to keep hundreds or thousands of cookies on your system, this extension is not for you. It is intended for people who typically keep relatively few cookies on their system at any given time (say less than 100.)
CookieKiller does not protect any cookies, so be careful not to delete cookies for sites that you want to keep.
See the Release Notes for more information about what's new in the latest version.
Please email the developer with any questions, problems, or suggestions. If I don't know about a problem, I cannot fix it.
*** NOTE: This extension is no longer in active development. I will try to correct any major breakages that may occur as a result of FF updates, but do not currently have the time to do any development on it beyond that.
