I use Chrome on Windows 10, visit Tables de Multiplication ⇒ à imprimer au format .PDF ou .JPG , following error message appears:
404 Błąd — nie znaleziono strony Sprawdź adres URL. W przeciwnym razie kliknij tutaj, aby przejść na stronę główną.
, instead Edgy should come active.
im pretty sure that isn't a major part of snap, so shouldn't this go in Mods and Extensions?
edit: the entire site "snap-apps.org" is gone. you sure thats the right website?
I've moved it to Mods&Extensions, because as @miniepicness says, Edgy is not maintained by the Snap! team.
In any case, you can still find it here: http://snapapps.github.io/edgy/
I think it's just their domain that's down.
