I wonder if it would be a difficult thing to add folder names to the searchable material within a user's Firefox bookmarks? It could potentially reduce the time required when trying to find a page that has a name or location you can't remember, and in some cases it may be the only way to locate it at all. Moreover, it's hard to imagine a very important reason for not including it. Perhaps some users would feel that the addition of folder names to the list of results from a search would add annoying clutter and length to the list. If that is true, then making the inclusion an optional feature for indexing and search preferences would keep the change from becoming cumbersome for them.
