Still working Rated 4 out of 5 stars
Used CM for a long time. Now on Fx 28. Still no problems.
"The only issue I have is every time I run CCleaner I lose the preferences for what sites are Allowed/Denied/Session."
That's not a Cookie Monster issue. It's the CCleaner preference to clean "site preferences" for Firefox - possibly other browsers. Uncheck that for Fx, Tbird, )other browsers?).
Site preferences are the same as exceptions (regarding cookies). The same thing would happen to anyone that checked to have Fx clean preferences at shut down, under Options > Privacy.
