In Firefox 22.0 bookmark subfolders diminish to the point of unreadability - why design such a thing?
The top row of bookmark subfolders are displayed where the parent folder's bookmark row is located. This means there is a limited amount of real estate in which to display all the rows of the subfolder. If the bookmark of the parent folder is near the bottom of the screen the subfolder's rows aren't viewable in-between the scrolling arrows. Suggestion: If the top row of the subfolder displayed as near the top of the screen as possible there would be no need to use the scrolling arrows to get to the desired bookmark in most cases. Is this possible on the next release? I'm using Firefox in Ubuntu 13.04.

With time one always ends with more bookmarks than the real estate can handle. Have you tried "Show all bookmarks" (Shift+Ctrl+O)? The library window, that opens, can be pulled to a separate workspace and used there, whenever needed.
You may find Tab Groups handy as well: Use Tab Groups to organize a lot of tabs
