I added a toolbar, but I still only have one toolbar with my various bookmarks on it. How do I get the second one I created to appear, and start adding bookmarks to the second one?

oh, you can only put toolbar buttons on that newly created toolbar, and without any button on it, it will be remove right away after you exit customize penal.

for multiple bookmarks bar, well, I normally just suggest ppl use folders on that bar, multiple bookmarks just goto different folders based on whatever standard you like.

NOTE, this KB'e method might not work, I am not sure


PS. another way of shorten the space each bookmark takes up is using a extension called smart bookmarks bar ( https://addons.mozilla.org/firefox/4072/ ), this can change the bookmarks into a single icon, and show fullname on mouse hover.
