Rated 5 out of 5 stars
It's the best speed dial for firefox if you ask me. there doesn't seem to be a lot of options but what you need is there, and the most important thing is that it loads very fast.
You can change the size of the boxes, or add extra boxes and have 50 or hundred sites on a tab all available at one click, but that wouldn't be so practical as it would be hard to find what you're looking for and beat the purpose of the add-on. Around 20 to 30 box addresses are optimal.
There's an option for sorting the boxes but the way you organize them will be best because you'll know where everything is.
You can install extra themes, but that way you will lose on speed.
Also there's an context menu entry Add to Fast Dial so you can add pages more easily.
All in all it does a great job keeping all you need close to a mouse click.
