Why am I getting BBC news when I clip on Latest Headlines?

You can go to your favorite news website and see if it offers an RSS feed. You can find an RSS feed button in the toolbar palette if you open the Customize window and drag the button on the Navigation Toolbar. Open the Customize window via "View > Toolbars > Customize" or via "Firefox > Options > Toolbar Layout" *https://support.mozilla.com/kb/Back+and+forward+or+other+toolbar+items+are+missing
