On my default or home page – the one that’s created when I type Cmd-T to open a new tab – there are half a dozen website icons. They look like sites I may in fact have visited in the past, but I don’t know how they got on to this default page and I can’t seem to remove them. These pages are NOT in my bookmarks list. The icons have delete buttons, but the delete buttons don’t work.
How do I get rid of these things?
