Rated 4 out of 5 stars
I really love this add-on, and have been using it for months.
Sadly, with the release of FF3.5, this add-on isn't nearly as helpful as it once was. Because now when you close the final tab, all of FF closes, instead of showing me SpeedDial like before.
Strange that this would still be a "recommended" add-on when Mozilla took away half of its potency for me.
This is fixed in the new version, 0.9.1, along with a couple of minor issues in Firefox 3.5.
