Great addon but not compatible with Firefox 20.This review is for a previous version of the add-on (188.8.131.52-signed).
Now compatible with Firefox version 20
Thanks for the review, demonex! Sparky 1.8.0 is compatible with Firefox 20 (and 21 beta). Find a pre-release version here: https://s3.amazonaws.com/com.alexa.toolbar/sparky-1.8.0.xpi
