Further thanks to you all for public and private messages of help, support or both (remembering the furore caused by and/or - but that was in another chunter and, alas, the thread is dead.)

My big problem now is my total lack of knowledge of "cookies" and where to find them, how to enable them, etc. As I say, it is a new machine - indeed the first bran new machine I have ever owned, all previous having been passed to me by affluent friends and relatives who could afford new ones for themselves. My detailed knowledge of computers dates back to a time nearer to Babbidge than to Gates so the software, and how to deal with it, is still shrouded by the opacity of the veils of my ignorance.
(It is a measure of my anguish that I, the egoistic and bombastic vegetative storm-trooper, will admit to ignorance about anything!)

So - recipes for cookies and how to cook them, please.
