Was just curious about cookies and what they are doig on my system, I know what they are and what they do but wondered how bad they are for privacy and as well as performace on my machine. I apparently have 2.6gb of cookies, that's a lot of 1s and 0s! I am now going to delete them, but wondered all this time, are all of these cookies recording my every move on the internet and selling this data back to advertisers so I can be easily targeted??? I have ad-blockers anyway, just wondered if there is a good cookie killer?? Or are there any settings in Firefox I have missed.. I did see I did not have the 'strict' controls set which I will do now. Thanks.
