It would be great, and less messy for when a user opens a bookmarks (sub)folder in the bookmarks sidebar to close all other opened (sub)folders, so only the current folder is expanded, which would make digging through them much less clumsy.

Reproducible: Always

Steps to Reproduce:
1. Open a bookmarks (sub)folder in the bookmarks sidebar.
2. Open another bookmarks (sub)folder in the bookmarks sidebar.
3. Why not close other expanded folders in the bookmarks sidebar, making navigation and layout less messy.
Actual Results:  
All kinds of open (sub)folders, need to close them all apart to get a serious overview of the bookmarks and bookmark folders.

Expected Results:  
Close all non-active (sub)folders when opening a new (sub)folder in the bookmarks sidebar.

This could be done by using the 3rd-party add-on called "Autoclose Bookmarks & History folders" found here : http://www.sephiroth-j.de/1/mozilla/

Would be much better to have this option right out-of-the-box.
