del.icio.us Extension for Firefox 2.0

For the past few months, since upgrading Firefox to one of the 2.0 betas, I've been somewhat lost without my handy del.icio.us integration courtesy of the official del.icio.us extension for Firefox (which isn't 2.0-compatible).

So it's with much pleasure that I discovered this morning the existence of an unoffical del.icio.us extension which has bags more functionality and works with the 2.0 branch!  Hurrah!
