Roy RainfordRecently I find that when I click on a link to a Web page, in Mail, it opens Safari on "uk.search.yahoo.com", not showing the page linked. There is just the empty search box and a blank page. However if I carefully click the edge line of the search box, not easy to position correctly, a list of ten previously visited Web pages appears below the search box. In that list is the page that I want and I have to click that to bring up the page. Before Yahoo started to appear I just clicked the link in Mail and I was quickly on the Web page required.
How do I stop Yahoo appearing? Can't see anything relevant in System Prefs or Mail Prefs.
Using iMac OS 10.13.6 High Sierra, Mail v 11.5, Safari v 12.0.3
