Rated 4 out of 5 stars

I've discovered a small bug that crops up with this extension installed on Firefox 3.5 RC2 with Windows XP... when this extension is installed and you open a local file(a web page stored on the hard drive i.e. - file:///location), an error box pops up as soon as the page finishes loading that says current_domain is null. It happens every time a local file is opened with this extension installed and enabled, and does not happen when this extension is disabled or uninstalled
