Rated 5 out of 5 stars

This Addon is the best to learn programing JavaScript !
I have greater than 15 buttons of this, each one is a Mini-FF-App...

BUT it doesn't work since FF-20...

Then, I keep my FF at 19.0.2 since this addon will be compatible with FF-20+

Really need update to survive...

This review is for a previous version of the add-on (0.0.5.5.1-signed).
