The bar below the address line has sites I don't use. Can the site tabs, or the entire bar, be deleted?
If you're using a computer, choose Hide Bookmarks Bar from the View menu.
You can remove the links in the bar by dragging them out, and add new ones by dragging them in. Also, you can use keyboard shortcuts to open the links: command-1 for the leftmost, command-2, and so on.
