Best Footnote plugin so far. But yet, there are some things, which makes it hard for me to use it.
1) Firefox doesn't seem to like it (instead of siplaying the footnote in the popup, it keeps diesplaying "Loading..."
2) I miss the feature, to have a backlink for every backref.
3) You could easily add an option to only show it in the fulltext mode by simply adding the style attribute "display:none" in the <div> surrounding the list.
