Rated 4 out of 5 stars
I was a long time user of this addon until a few months ago when I kept getting errors in the logs of firefox 3 and it seemed that speed dial was using so much memory it was even causing my mouse cursor to keep changing to a timer whilst firefox was being used!!
It was something to do with the speed dial browsing in the background as far as I could deduce!
Anyway I now return to it with a fresh install of the latest firefox and I have to say it's better than ever. NO memory or CPU problems at al. Runs smoothly and it a great addon, really useful. And better than that other one! Ha!
