We've just released 1.0.6 of the firefox addon (you can get it here)

It has minor bug fixes, a first time run checker but more importantly it works with latest beta of Firefox 3.5

With over 135 weekly downloads, it's not bad for being in the Sandbox i.e. experimental zone.

On that note a top tip for getting out of the sandbox which I got from a mozilla addon
"release early, release often"
This came straight from an Addon Editors over the weekend. Don't be afraid to upload new version .. it won't be put to the back of the queue!  We hope to be out really soon!
