/* How to hide "Recently Bookmarked"
   This effects booth the Bookmark icon and pulldown.
   A menu item switches a hidden preference from true to false, and you can do that directly as follows:
    (A) In a new tab, type or paste about:config in the address bar and press Enter/Return.
        Click the button promising to be careful.
    (B) In the search box above the list, type or paste book and pause while the list is filtered
    (C) Double-click the browser.bookmarks.showRecentlyBookmarked preference to switch the value
        from true to false
