The problem has disappeared for me on my PC after disabling that-which-shall-not-be named here (which didn't seem to help) and then re-enabling it. Odd!
The problem DOESN'T occur on my Android phone, using Chrome (and without that-which-shall-not-be-named-here).
The problem seemed to have disappeared (I checked out lots of different threads)but, as soon as I posted about it the 'Privacy' message reappeared. Odder and odder!
