The addon stopped working for me with Firefox 20 @ Ubuntu 12.04. I got it working again by disabling the 'Tilt' addon. Users with similar problems should try disabling all addons and enable one by one to see if there are addon conflicts.
Love this addon, could not survive without it. Therefore I also suggest that we should donate to keep the addon alive :)
