Rated 5 out of 5 stars

It is fast and it uses a very small amount of resources, provides a refresh every minutes or whatever duration that can be set. Thumbnails can be refreshed or use your own pictures. Javascript can be enable to make the thumbnail more accurate. Settings can be set and change easily according to user preferences, for example, you can set a 3x3 as a speed dial or even 3x4 or 4x4 and more, all with a few clicks. Lastly, many tabs in the speed dial can be organized, it almost replace my bookmarks.

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