Rated 5 out of 5 stars
Download Nubs does the job indeed yet it's on a very early stage at the moment. Still hoping for Download Statusbar update yet, even though Mozilla forums opinions tend to suggest that due to Firefox modification it is harder and harder to produce an add-on that meets the new requirements.
Update needed! Rated 5 out of 5 stars
Excellent add-on - I've been using it for almost ages now.
But it needs an update to get working in FF 26 as it's not visible in the statusbar of this version.
