Sorry for posting this if it's been posted before (as I'm sure it has!) but when I did a search, the list that was presented was over 2 pages long with no Title indicating just what I was searching for. Whenever I go into Settings\Safari\Advanced\Website Data\Show All Sites and scroll down far enough, I will see an entire series of entries like a####.phobos.apple.com where the #### ranges from two to four digit numbers. Each entry is only 0.3 KB but there are well over 100 of them and they seem to be multiplying! From the other entries on the list, it appears they correspond to website cookies. What is phobos.apple.com? Is there any easy way to remove all the entries without also removing everything else?
