Speed Dial by Josep del Rio

Direct access to your most visited websites

Collector's Note Superb, must have, this dial can replace your favorites/bookmarks. This is the best dial for Firefox (I have 518 dials in 15 groups), fully customizable and full of excellent features (Create groups, colorize you group tabs, different background for each group, and lots more) but the thing that makes it the best is not all these features only. It's the ONLY dial that allows you to import/export your settings and dials, so you can export your dials and settings to USB flash, install speed dial on any computer, do an import of your settings and dials from your USB flash and you are good to go, FURTHER MORE, it does interval backups of settings & dials on it's own, nothing beats that dial for me.
