melhor que tem, pena que só tem versão em inglês, mas o tradutor do google consegue traduzir.

Rikaikun has been a life saver for over a decade. I do have one problem... Recently it keeps resetting the highlight text setting, which is really annoying when you're trying to fill out a form and the text boxes keep losing focus. Not sure why this suddenly started happening, but it's the only problem I've ever had with the extension since it was first released.

This is amazing!(I would only work on adding popular authors’ and historical figures' names and book titles etc. to the database) (Also, when I try to copy paste with my keyboard, the extension bubble shows up, because I press SHIFT A or SHIFT V and then ENTER) Otherwise, this add-on saves lives. Thank you so much for the effort of making it!

é uma ferramenta muito útil para ler textos em japonês, tem de saber ler em inglês também, mas isso não é culpa dos desenvolvedores podia haver em outros idiomas, seria bom
