Outdated Rated 3 out of 5 stars

Even version 0.6.5 available on the developer's page is problematic -- here anyway (Firefox 5.01) but I don't see any add-on conflict - when some icons are simply missing on the status bar (set to be shown from the add-ons' options and not set hidden by OSBar). Would be nice that the developer keeps up with this extension because I think we are many to like it.

There is a 'Organize Status Bar' ver. 0.6.5 with maxversion set to 4.0.* that works perfectly well on brand new beloved Firefox 5.0 :)
It's on the developper's site as mentioned above :
