until now I´ve used "Cookie Quick Manager" which sadly seems not getting any further development. So I´ve switched to "Vergiss mein nicht" since a few weeks, and on the whole it´s an easy to use, innovative AddOn.

But something is nevertheless going wrong here, bc every few days some with "[N]ever" protected cookies and their stored website-data are gone and I can input every website-specific stuff once again. Any possible other, auto-erasing possibilites, cache-cleaner etc. are disabled here.

With "Cookie Quick Manager" that -never- happened, secured cookies were reliable stored over -months- there. So I´m clueless and not really happy with this AddOn right now. :(
