Works well, but does not include romanization of hovered word. Also does not work for dynamically inserted content.

Es en verdad útil para principiantes con 漢字. Por otro lado, está incompleto, no deja agregar diccionarios etc. y no ha sido actualizado desde enero de 2012

Exactly what you need if you understand enough Japanese but are still stuck with not knowing enough kanji - thanks!

When there are verbs like 来ない, or other conjugated forms of a verb, it would be nice to see its pronunciation, especially if there are multiple pronunciations for the base verb, but only one that fits the conjugated form. Like for 回る, which can be either まわる or もとおる. They can be differentiated in some conjugations, and it would be nice to know the exact pronunciation then
