My cookies are being deleted very regularly perhaps two times per week and very often it seems to occur after one the the very frequent updates are installed. I have tested this by refusing an update for several days and the cookies remain, but after i accept, often, they are deleted. I have not changed any settings related to cookies at any time and so it does appear that the updates are the couse. there cookies are very useful and include preferences for websites and identification details and it's incrediibly frustrating to have them erased though no fault of mine
