I've just migrated from Ubuntu Jaunty.
I've reinstalled my favorites FF add-ons and I'm surprised to see that the Smart Bookmarks Bar doesn't work.
It looks correctly installed as I can see it in the list of add-on, access its preferences etc; but the shortcuts on my bookmarks bar are not minimized as they should be (which is the purpose of this add-on).
Add-on page: https://addons.mozilla.org/en-US/firefox/addon/4072
Any idea what could cause the problem?
