BUT there's one big drawback, for me anyway, if you click on a 'bad' (as in no such page) bookmark in the sidebar then the error is displayed in the sidebar rather than in the main Firefox display area and I can't find any way to get the bookmarks back in the sidebar except by pulling the View menu down again.
Press "Backspace" or the "Back page" button if your keyboard has one?
HTH Tim.
