Rated 5 out of 5 stars
GUESS What Folks... I've just installed this extension on ff 3.0.1, and it works fairly well. There's no plugin like this one (NOT Organize statusbar NOR Statususable).
This is absolutely the best StatusBar Organizer HANDS DOWN!
P.s. I installed this plugin by clicking the Ignore version check link under the "Add to Firefox" button on this page. And I used MR Tech Toolkit to remove the version check.
I hope this info helps someone like me.
