So your answer is that Firefox has no built in function to verify bookmarks?
Secondly
When I imported my bookmarks from my MS browser into Firefox they were 
all organized in folders just like they were in the MS browser. Now when 
to go to export Firefox bookmarks I get them listed in URL sorted order 
missing there organized folders. This is not acceptable. Need to have 
them exported grouped in their folders as Firefox shows them.
How can I get this accomplished?
Where does Firefox store the raw bookmarks html file? This file must be 
like a directory tree with each folder being a sub-directory.

Does any one know of any Firefox addon's that address these problems 
with Firefox bookmarks?
