Latest version has some issues Noté 4 sur 5 étoiles
It was easier to use before this unneeded upgrade. And please get rid of the Green Jigsaw piece in the Add On Toolbar. If anything, it should Only Show up when an Add On is detected as Incompatible. Also I have Google Toolbar and it is working. I found and put a Check Mark next to it on your little green piece, but Add Ons Manager still shows as Not Compatible.
Get this fixed, please. Same for the Firefox 3 Theme For Firefox 4+ ... it does work, but Add Ons Manager says it will not.
