Cleans most cookies effectively, but seems not to pick up all of them because I have to use CCleaner's cookie cleaning tool to remove residual cookies that are missed.

The controls are great, as is the ability to export white/greylist backups. It would be good if Firefox sync could be used to keep these lists across the different computers in my FF account. Some of the options are a little obscure, particular with regard to how Cookie AutoDelete works with FF containers.

It would also be good, in the case of a red label on the blue icon, which cookies fall outside of the whitelist and are to be deleted.
