Rated 4 out of 5 stars

This is a great addon that speeds up my daily browsing. I've memorized the bookmarks on my first group, and regularly use the Ctrl + (Shift) + [Number] shortcut. This addon is one of why I returned to Firefox, after a brief foray with Chrome. Chrome doesn't have a speeddial extension that offers this functionality. I have five other groups, that I use as a visual resource, organized by theme and color coded. BUT Speed Dial would be even better: (1) if it were easier to add new bookmarks to firefox mobile (perhaps by using a long-press) AND (2) if there were a way to sync groups across multiple devices. In these times that functionality is highly desired.

This review is for a previous version of the add-on (0.9.6.4.1-signed).
