So, I got the upgrade box and clicked update. Problem was that my bookmarks were loaded from an… old back-up. Since, like everybody else, recent missing bookmarks are rather important, I wanted them back. Fortunately, Google pointed the way. These two links (1 + 2) helped me. I used the “Manual deletion method” which worked straight off.
That said, I’m not too enthused about the new look and feel. Perhaps I’ll get used to it, perhaps not. But, to me as a first impression, it looks too much like Safari. We’ll see.
