thru the last week some Sites forced the Safari preferences to accept any cookie and they placed a lot.
i had to kick em out again and again, even the preferences where overwritten each time and my HISTORY was not visible in the drop down menu. Some sites like MACKEEPER are top suspects.
i hope Apple can fix this with the next update. by the way i tried some Blocker Apps, did not help.
there was a report too of some hackers
P. S. Ssomeone wrote into the the File Library/Safari/HistoryIndex.sk
delete and safe, the History appears again.
And here are the the last suspects to the Safari Preference Hack
after this cookie
a cookie named > indexx.org appears as written
then comes a cookie from > media-serving.com
and last they drop this cookie > utop.it -seems to be a Italian Server
