I have mozilla-firefox 3.01 bookmarks which contain folders ANIMALS and THINGS BEGINNING WITH D.
I want DOGS to be a subfolder of both ANIMALS and THINGS BEGINNING WITH D.
But when I add a new entry to the DOGS folder underneath ANIMALS, I want the DOGS folder underneath THINGS BEGINNING WITH D to be automatically updated. In other words, there should be only one DOGS folder but there should be links to it from the ANIMALS folder and from the THINGS BEGINNING WITH D folder.
How can I do this?
