Is something wrong with the Zemanta extension?

Zemanta was not loading -- not even in the browser bar -- so I uninstalled and went to re-install it. I keep getting a message reading "Firefox could not install the file at

because: Unexpected installation error
Review the Error Console log for more details

indifferent I’m vaguely concerned
