Alternatives to ScrollyFox Rated 5 out of 5 stars

EXCELLENT SOFTWARE! I've found this so useful when reading stories on the web. But since the developer is no longer keeping up with new versions of Firefox, does anyone know of an alternative? Someone mentioned "scrollloper", but that does not actually seem to exist? Was it misspelled?

This review is for a previous version of the add-on (2.3.1-signed.1-signed).
