I am using the latest version of Collusion on firefox version 17.0.1 on OS X Mountain Lion. I use firefox in a private browsing mode and with other addons: adblock plus, betterprivacy, ghostery, noscript and flashblock. Every time I open firefox and click collusion, it shows the following sites following me: google.com, youtube.com. ytming.com, newsy.com. However, I can't find any cookie relating to these sites on firefox. Could anyone help resolve this? Many thanks.
