I use Win 7 Ulti, Ff 60.3.0 esr After cleaning cookies with cclener AND Ff "Cookies Exceptions", there are still 4 cookies left unremoved. One is the s.uind.com which I believe comes from the web/.de/gmx.de owner 1&1, another two are named with a 30 digit code, 94b0ab62-511d.4be8-a2e3-c46619f3220c is one of them. Is there a way to find out what and from where they are? Can they be permanently removed? I can of course remove them manually in ccleaner before shutting down, but after the next re-start of the computer and ONLY switching on ccleaner, they are already there again..... Thanks....
