Broke my Firefox. Rated 2 out of 5 stars

I installed this January 15, 2010. I then restarted and Firefox would start but never bring up any page, display my add-ons nor respond to any clicks. I tried several times, cleaned my registry and I reinstalled Firefox. Still nothing. I eventually tracked down the folder for this extension and manually moved it temporarily and started Firefox and it finally ran and brought this page back up for me to tell you what happened. (it was an open tab when i restarted).
