Here i am mentioning some of the firefox add-ons which makes me say ‘Wow’ in a not geekish way. Though this is late but i found them just today and could not restrain myself from sharing these to all 
.
Cooliris
Full-Screen, 3D — Cooliris transforms your browser into a lightning fast, cinematic way to browse online photos and videos.
This takes image/video searching in a new height. Must see.
It’s better than FastDial in sense of look … But i like them both. 
Let me know if you have seen such kind of innovative add-ons or application .. Do share.
