Rated 5 out of 5 stars

this addon seams to have it all covered.
speed dial, background image, css, export/import of settings, undo the last closed tabs, quickly add a tab to super start, groups of tabs.. really just right. the speed dial page i needed and i can now disable a few other addons and somewhat simplify firefox.

This review is for a previous version of the add-on (6.1.1-signed).
