Супер!

good

Just what I wanted, nicely implemented. However, I can't figure out what the "Use local Google site" option does.

Amazing!

It works great and as advertised!

Seems perfect to this moment.

Excellent add-on, most useful. Doesn't seem to work on TinEye though.

un clic droit pour lancer la recherche d'images à partir d'une image repérée sur le web ... et hop, elles apparaissent ! Soit on cherche pour plusieurs moteurs de recherche en une fois (il y a autant de fenêtres qui s'ouvrent que de moteur), soit on cherche à partir d'un seul moteur !!!
C'est super rapide et bien pratique ...

Even better than expected.

Works great, looks neat. Best image search addon i've seen to date.

Well customizable, multiple engines, works well with firefox 57+.

Good, but I wish i could choose the position of the entry in the context menu, instead of having it at the bottom.

Apparently this can't be done because of the API's limitations, so I guess there is nothing to do.

Thanks for this.
Would it be possible to add karmadecay?
