bookmarks pulldown should stay open

[mdrum]

It is extremely hard to use the bookmarks hierarchy in Firefox. When you try to drill down into it, the whole pulldown-tree disappears, or dives down into some other subtree that you're not interested in, unless you very carefully keep the cursor exactly within the item you are trying to expand. It would be much nicer if, when you click on bookmark-folder, it stayed open, without careful mouse-dragging, until you click somewhere else (or hit escape). Thanks for listening.
