I really want to like this add-on because the concept is great and the interface is good; however, there is a huge flaw. I will delete a cookie from a given website like Youtube using this Cookie Quick Manager but when I go into my Preferences>Privacy Security>Manage Data and open the folder, THE COOKIES ARE STILL THERE :(

I generally love Firefox but I am furious how they changed the cookies. They used to be so easy to delete but now you have to jump through a lot of excessive hoops to delete your cookies. This is a nefarious attempt to favor tracking your behavior and is total garbage. I was hoping this add-on would liberate me from the cookie fiasco created by Firefox but I don't think it works for the aforementioned reason.
