How do I get bookmarks to display on left side of screen

I would like to get the bookmark section back on the left side of the screen which is a much more convenient spot for my application. It appears mozilla has discontinued this, why? The bookmark saving is cumbersome at best. It makes no sense to remove things that work for something that is not necessarily better.
