What must I do to delete an unwanted entry in the "Name" column of the Bookmarks Toolbar list in my Bookmarks Library? At the very bottom of the entries in the "Name" column of the Bookmarks Toolbar in my Bookmarks Library, an entry has appeared which looks different and behaves differently than all the other entries. And I cannot delete it. All of the other entries have either a small icon or an empty square symbol at the left-hand end of its row. This bottom entry has nothing at its left-hand end. It reads "7/13/14- Profile folder - Thunderbird - MozillaZine Knowledge Base". And if I double-click any of the other entries, that action opens its web page. If I double-click this bottom entry nothing happens. If I right-click this bottom entry, the menu that appears includes a Delete command, but it does not disappear if I try to do that. And if I add a new bookmark to my Bookmarks Toolbar, it does not appear in the list which is displayed in Firefox, but it does appear beneath the entry "7/13/14- Profile folder - Thunderbird - MozillaZine Knowledge Base". In order to make the new bookmark show up in the list which is displayed in Firefox, I must open the Bookmarks Toolbar in my Bookmarks Library, scroll to the bottom of the Name list, and drag the new bookmark up past the "7/13/14- Profile folder - Thunderbird - MozillaZine Knowledge Base" entry. Again, how can I get rid of this unwanted entry?
