Steps to reproduce:
Use Aurora/Nightly as usual, dragging bookmarks into the nine speed-dial slots(Since I have Firefox set not to record history)
Thumbnails never appeared, I just saw blank boxes.
Screenshots of the websites should have appeared in the boxes.
This is surely related to one of those bugs regarding using the cache as thumbnail storage. Will be fixed by bug 744388.
