Can't remove entirely Noté 1 sur 5 étoiles

I removed this extension, but it has still apeared in my extension list with 2 links - "restart" and "cancel".But nothing changed after I clicked any of these 2 links.And it revived after my firefox upgraded. So I use "organize search engines" instead, and I feel it's better than this one.

Cette critique concerne une version précédente du module (0.4.6.1-signed).
