Can pin selected cookies of one domain and abandon all others. Rated 5 out of 5 stars

Still installs and works fine in FF 26. Only Cookie Add-On I found that allows to keep CERTAIN cookies for a domain (like login name) but delete other cookies (like tracking) for the same domain when closing the browser.
Unfortunately no development since 2009. General UI polishing would be great. I'd like to be able to browse while Cookie Culler's main window ist open. Could have some more options, e.g. a link to see for which sites cookies are blocked. BUT: gets the job done. (I don't need cookie editing features for daily browsing, there are other Add-ons that specialize on web development or pentesting.) Thanks, Dan!
