I give you 3 stars because potentially it's the best speed dial I found on firefox
but for now still missing some crucial options for me.
First of all I like that it's really fast, I like the thumbnails,
what I don't like, when I add a dial I want that as ultimate,
not as first, then it would be great to have more options to customize,
like the numbers of columns.
Then it would be great to have the possibility to make group,
just like the speed dial in opera when you can add multiples dials in one major dial
with drag and drop. Then last thing but not that important, a search bar.
