Great Concept, but falls short. Rated 3 out of 5 stars
I just started using FireFox again after 2+ years using OPERA. The only reason I'm back is OPERA has compatibility issues with too many sites, otherwise, IMHO, it is far superior to FF (Speed & Customization Ability--buttons,menus,etc...).
This is just like a phone call from home! I missed this feature, but now I got it back, I thought. Upon further testing it seems I'm having the same problem with the bottom panel in FF3.03 as reported by Jaime Davila below.
This renders this extension totally useless.
Needs immediate attention!
