The Multirow Bookmarks Toolbar does the same thing but for the bookmarks toolbar. This addon allows you to have any number of rows of bookmarks. This is for those who likes to keep lots of bookmarks in front of his eyes, much more than the toolbar can accommodate. With this addon, space isn’t a problem. However, make sure that you have enough screen space left to read the web page.
You can limit the height of the toolbar by editing the userChrome.css file.
In case the height of the toolbars exceed the maximum height defined in
userChrome.css, a vertical scroll bar will appear. So you can have as
many rows of toolbars you want within the space you define. If you know
CSS you can also add your own styles by editing this CSS file.
