Rated 4 out of 5 stars
This addon is just indispensable to me ! saves LOT of space, especially on my notebooks, but appreciable on my desktop too.
The behavior of this addon must be integrated into the firefox default options.
PROBLEM: Not compatible with Firefox 4 at all, doesn't install, but if forced it still doesn't work :/
PLEASE fix it for firefox 4 ! :)
( For now i use Roomy Bookmarks Toolbar, but it not work fully, for exemple the space-between-icons option has no effect :/ )
